Streszczenie:
Tungsten diboride alloyed with transition metals provides an opportunity to obtain exceptional mechanical, physical, and chemical properties. We report a strategy for designing and synthesizing of superhard and low-compressible ceramic thin films with increased toughness and lowered residual stresses (σ < −0.9 GPa) deposited with high-power impulse magnetron sputtering (HiPIMS) from one target. The addition of 7–12 % titanium promotes additional strengthening mechanisms of the layers in one material, leading to the improvement of wear resistance compared to an alloyed WB2-z yet at even higher hardness 43.8 ± 2.1 GPa and nanoindentation toughness 4.9 ± 0.2 MPa√m. The compression of the micropillar shows that titanium addition changed the type of nanoindentation from cracking along the slip plane to bulging on the top of the pillar and next the crack initiation along column boundaries. The highest adhesion of the layers is obtained for addition of 7 % titanium and in all cases the wear has abrasive character. The controlled use of 200 μs pulses during synthesis with HiPIMS allows for an increase in the deposition rate and maintaining exceptional mechanical properties of the layers even at a substrate temperature of 300 °C.

Streszczenie:
We present the deposition and characterization of tungsten-tantalum diboride (W,Ta)B2 coatings prepared by the high-power impulse magnetron sputtering technique. We evaluated the influence of pulse duration and substrate bias on the properties of (W,Ta)B2 films. A high hardness of up to 35 GPa measured by nanoindentation was simultaneously obtained with good elastic properties. Changing the pulse duration greatly affected the B/(W+Ta) atomic ratio, which influenced the properties of the coatings. The deposited films are thermally stable at up to 1000 ◦C in vacuum and are able to withstand oxidation at 500 ◦C.

Streszczenie:
Potentially superhard W1−xZrxB2 polymorphs, hP6-P63/mmc-WB2 and hP3-P6/mmm-WB2 , were thoroughly analyzed with zirconium doping in the range of x=0-25%, within the framework of the first-principles density functional theory, from both a structural and a mechanical point of view. The obtained results were subsequently compared with the properties of material deposited by the magnetron sputtering method. All predicted structures are mechanically and thermodynamically stable. Theoretical calculations suggest a decrease in hardness Hv and fracture toughness KIC of the hP6 phase with zirconium doping but no such effect on the hP3 phase. It was observed that an additional defect in the analyzed structure significantly weakens the hP6 phase but strengthens the hP3 phase. The deposited films are characterized by greater hardness but lower fracture toughness. The results of experiments show that not only is solid solution hardening responsible for strengthening the predicted new material but also the change in microstructure, the Hall–Petch effect and vacancies.

Streszczenie:
Magnetron sputtered WB2 coatings doped with 8, 11 and 16 at.% zirconium were analysed using energy dispersive spectroscopy, X-ray diffraction and nanoindentation under the load of 4, 7 and 10 mN. It has been observed that these coatings crystallize in the α-AlB2 and ω-W2B5 prototype structure. Phenomenon responsible for this is an increase of the zirconium content which causes an increase in the ω-W2B5 phase. All the deposited coatings have a hardness of about 45 GPa while Young's modulus drops down from 497 to 480 GPa with increasing zirconium content. Coatings without doping and doped with 16 at.% zirconium were annealed at 650 °C and subjected to cyclic thermal loads using a maximum temperature 600 °C and cooling with a compressed air. It has been observed that addition of zirconium improved coatings phase stability.

Streszczenie:
In this work, novel W-Zr-B coatings were developed by a hybrid process combining pulsed laser deposited ZrB2 and radio frequency magnetron sputtered W2B5. The influence of the laser power density on the structure and mechanical properties of the deposited films was studied. Addition of zirconium causes a change in the structure of the deposited films from columnar to mainly amorphous. The nanoindentation tests and compression of nanopillars showed that doped W-Zr-B layers are still super-hard and incompressible in comparison to WB2 films without doping, but they change their behaviour from brittle to ductile. Films obtained with a fluence of 1.06 J/cm2 are superhard (H = 40 ± 4 GPa) and incompressible (12 ± 1 GPa), but possess a relatively low Young’s modulus (E = 330 ± 32 GPa) and a high elastic recovery (We = 0.9). Further increase in the fluence causes films to consist of deeply embedded fragments of laser ablated ZrB2 target in the deposited layer. Taking into account that the particles are made of ZrB2 which possess extraordinary thermal properties, and the matrix is made of W-Zr-B, a super-hard material, such a composite can also be interesting for industrial applications.

Streszczenie:
Tungsten borides (WBx; x = 2.5 or 4.5) with an increasing substitution of tungsten by zirconium from 0 to 24 at.% were synthesized by spark plasma sintering (SPS) for the first time. The influence of the holding time (2.5–30 min) on the densification behavior, microstructure evolution and development of the properties of W–Zr–B compounds were studied. The samples were characterized using scanning electron microscopy (SEM) for microstructure analysis, X-ray diffraction (XRD) for phase identification, Vickers micro-indentation for microhardness measurements, tribological tests to determine the coefficient of friction and specific wear rate, as well as measurements of electrical conductivity. The XRD results confirm the presence of the WB4 phase in the microstructure, despite the high sintering temperature (1800 °C) and small overstoichiometric excess of boron (4.5) addition in the sintered samples. This is caused by the high heating rate (400 °C/min), short holding time (2.5 min) and addition of zirconium. The Vickers hardness (HV) values measured at 1 N are 24.8 ± 2.0 and 26.6 ± 1.8 GPa for 24 at.% zirconium in WB2.5 and for 0 at.% zirconium in WB4.5, respectively. In addition, the hardest sample (W0.76Zr0.24B2.5) showed electrical conductivity up to 3.961·10^6 S/m, which is similar to WC–Co cemented carbides. The friction and wear test results reveal the formation of a boron-based film which seems to play the role of a solid lubricant.

Streszczenie:
To enhance the properties of tungsten diboride, we have synthesized and characterized solid solutions of this material with chromium, molybdenum, rhenium and zirconium. The obtained materials were subsequently deposited as coatings. Various concentrations of these transition metal elements, ranging from 0.0 to 24.0 at.%, on a metals basis, were made. Spark plasma sintering was used to synthesize these refractory compounds from the pure elements. Elemental and phase purity of both samples (sintered compacts and coatings) were examined using energy dispersive X-ray spectroscopy and X-ray diffraction. Microindentation was utilized to measure the Vickers hardness. X-ray diffraction results indicate that the solubility limit is below 8 at.% for Mo, Re and Zr and below 16 at.% for Cr. Above this limit both diborides (W,TM)B2 are created. Addition of transition metals caused decrease of density and increase of hardness and electrical conductivity of sintered compacts. Deposited coatings W1−xTMxBy (TM = Cr, Mo, Re, Zr; x = 0.2; y = 1.7–2) are homogenous, smooth and hard. The maximal hardness was measured for W-Cr-B films and under the load of 10 g was 50.4 ± 4.7 GPa. Deposited films possess relatively high fracture toughness and for WB2 coatings alloyed with zirconium it is K1c = 2.11 MPa m^1/2.

Streszczenie:
In this work, α-WB2 and (W,Ti)B2 borides were applied as wear-resistant coatings to commercial WC–Co cutting inserts. Properties of coatings deposited by magnetron sputtering on WC–Co tools were studied. The crystal structure and chemical composition were analyzed. Vickers hardness and surface roughness were determined and wear test in semi-dry conditions was performed. The W–B and W–Ti–B coatings deposited on WC–Co substrate were smooth and very hard. However, titanium alloy W-B films with Vickers hardness of 3630 ± 260 HV0.02 were characterized by lower adhesion to the substrate, influencing the wear mechanism. Turning tests carried out on 304 stainless steel showed that the W–B film caused less wear compared to uncoated insert. Moreover, when W–B coating was applied, flank wear was reduced by 30% compared to uncoated WC–Co insert. Additionally, coating prevented chipping of the edge during cutting under test conditions. The research shows that W–B film deposited by magnetron sputtering has great potential as a coating for cutting tools for difficult-to-cut materials.

Streszczenie:
In this work, (W,Ti)B2 films with different stoichiometric ratio Ti/W deposited on silicon and 304 stainless steel by radio frequency magnetron sputtering are presented. The coatings were deposited from plasma spark sintered targets obtained from the mixture of pure boron, tungsten and titanium powders. It is shown that during plasma spark sintering process using overstoichiometric boron and a low content of titanium change the WB2 to WB4 phase with almost no secondary phases. Subsequently, the impact of titanium content on the films properties is investigated systematically, including the chemical and phase composition, crystalline structure, surface and cross-section morphology. Simultaneously, nano-indentation test and ball-on-disk tribometery are performed to analyse the hardness and tribological properties of the films. It is shown that deposited films with titanium content of 3.6 and 5.5 at.% are formed in the zone T of the Thornton's Structural Zone Model. In opposite to α-WB2 magnetron sputtered coatings they are more flexible and hard nanocomposite coatings. The results show that the addition of titanium is apparently changing the film structure from nanocrystalline columnar to amorphous, very dense and compact structure with the addition of TiB2 phase. That films are simultaneously hard (H > 37.5 GPa), have high hardness to effective Young's modulus ratio values (H/E* > 0.1) and elastic recovery (We > 60%) appropriate for tough and resistant to cracking materials. The presented (W,Ti)B2 films exhibit also tribological and corrosion properties better than unalloyed coatings.

Streszczenie:
With increasing demand for high-performance and long-lasting cutting and forming tools, the members of this expanding class of superhard metals hold promise to address the shortcomings of traditional tool materials. Those shortcoming include their high cost (silicon nitride, cubic boron nitride, and diamond), their inability to cut ferrous metals due to chemical reactions (diamond), instability in the presence of humidity (cubic boron nitride) and relatively low hardness (tungsten carbide). Also the increasing industrial demand for protective coatings with high hardness, good elastic properties and thermal stability calls for the investigation of new material systems. Although transition metal (TM) nitrides are successfully applied for different tasks in automotive or aero-space industries, the search for improved materials is an ongoing topic, being far from its end. In this work the study on deposition of thin films made of new super-hard materials (SHM) such as tungsten boride are presented. Additionally, the influence of doping by titanium of those materials is investigated. Investigated films were deposited by the pulsed laser deposition method. The used targets were synthetized by SPS method. The powders of boron and tungsten in 4.5 to 1 molar faction were used. The films deposited by PLD method have stoichiometric composition such as used targets. The WB2 and WB3 phase are dominant. Research carried out using SEM, XRD and nanoindentation test showed that the phase composition of the targets is more important in the case of laser deposition than magnetron. All obtained layers are very hard and thermally stable. In the case of magnetron sputtering, smooth layers were obtained while the layers deposited by the laser have a very high roughness. Titanium doping increases the amount of WB3 phase in the sintered discs, while it has no significant effect on the properties of the deposited layers.
Z rosnącym zapotrzebowaniem na niezawodne, a jednocześnie zapewniające dużą wydajność, narzędzia do skrawania i obróbki plastycznej, coraz większego znaczenia nabiera rozszerzająca się grupa supertwardych ceramik przewodzących prąd. Materiały te dobrze rokują w związku z rozwiązaniem problemów tradycyjnych materiałów narzędziowych, których niedoskonałości obejmują wysoką cenę (azotek krzemu, azotek boru), niezdolność do cięcia stopów żelaza w wyniku reakcji chemicznych (diament), niestabilność w obecności wilgoci (azotek boru) i względnie małą twardość (węglik wolframu). Również rosnący popyt na powłoki ochronne o wysokiej twardości, o dobrych właściwościach sprężystych i stabilności termicznej powoduje, że badania nad nowymi systemami materiałowymi prowadzone są coraz intensywniej. Pomimo że azotki metali przejściowych są już z powodzeniem stosowane do różnych zadań w przemyśle samochodowym i lotniczym, poszukiwanie ulepszonych materiałów jest tematem wciąż aktualnym. W pracy przedstawiono badania nad osadzaniem cienkich powłok z nowych supertwardych materiałów (SHM), którymi są borki wolframu. Dodatkowo zbadano wpływ domieszkowania tych materiałów tytanem. Warstwy osadzane były metodą ablacji laserowej PLD. Tarcze do osadzania zsyntetyzowane zostały metodą spiekania plazmowego SPS proszków boru i wolframu o stosunku atomów 4,5 do 1. Osadzane z użyciem lasera warstwy mają skład stechiometryczny podobny do użytych tarcz. W warstwach tych dominuje faza WB3. Badania przeprowadzone z użyciem SEM, XRD i nanoindentacji wykazały, że skład fazowy tarcz jest odwzorowany w warstwach osadzonych laserem. Wszystkie uzyskane warstwy są bardzo twarde i stabilne termicznie. Warstwy osadzane laserem odznaczają się dużą chropowatością. Domieszkowanie tytanem zwiększa ilość fazy WB3 w spiekanych tarczach i osadzanych warstwach oraz zmniejsza ilość i wielkość naniesionych na powierzchnię cząstek.

Streszczenie:
In recent years, the search for improved materials for green energy, aerospace and automotive has been the focus of interest of scientists and industry. As an example transition metal borides such us ZrB2, TiB2, WB2 can be mentioned with their extraordinary thermal, mechanical properties and oxidation resistance even above 500˚C. Also in the form of thin films they are competitive with commercially used nitrides. The last studies have been show that disadvantages like low fracture toughness can be improved by alloying them with other transition metals TM= Ti, Cr, Zr, Mo, Ta, Hf etc. or the choosing of suitable deposition method. In this work the doping of tungsten diboride with titanium is presented. Also, two different method of deposition like High-Power Impulse Magnetron Sputtering (HiPIMS) and hybrid PLD-MS, which give possibility to produce a plasma with the higher energy than conventional DC magnetron sputtering are studied. Such solution allows to obtain coatings which are very hard and fracture resistant simultaneously. Deposited by HIPIMS coatings are smooth and possess lower hardness (40 GPa) than films deposited with PLD-MS method (51±8 GPa). However produced by hybrid method films are rougher and are characterized by higher Young modulus (520 GPa vs. 354 GPa) what cause that they are characterized by lower fracture resistance. Additionally, HIPIMS crystalline films can be obtained in 300˚C (520˚C for PLD-MS) what increase possibility of their future application. I should be noted that tungsten borides have very high potential for its implementation as a wear protecting coatings on tools and also in nuclear energy solutions
