The article includes research results for the functional properties achieved a wide range of sintered tool materials, including carbides, cermets and three types Al2O3 oxide ceramics ((Al2O3 + ZrO2, TiC SiC(w)) with (Ti,Al)N coating deposited in cathodic arc evaporation (CAE-PVD) method comparison uncoated materials. For all coated samples, uniform wear pattern on shank was observed during meta...

H-13 steel surface was duplex-treated using Plasma Nitriding (PN) and PVD coatings to solve the thermal fatigue problem faced in die-casting applications. Chromium-based multilayer CrN/Cr (m-CrN) multi-component aluminium–titanium-based AlTiN (m-AlTiN) were deposited a cathodic arc deposition technique after plasma nitriding with different case-depths of 50 µm 200 µm. The structural, tribologic...

Titanium-based nitride physical vapour deposition (PVD) coatings, such as titanium (TiN), are state-of-the-art solutions for surface modifications of CoCrMo-based implants patients who hypersensitive to metallic ions cobalt, chromium and nickel. Variations the process parameters during cathodic arc evaporation known exhibit an impact on properties coatings. The aim this study was characterise e...

An alternative approach for producing a hard TiB2/TiC multilayer on M2 high-speed steel was introduced by combining cathodic arc physical vapor deposition (CA-PVD) and reduction thermal diffusion-based boriding (CRTD-Bor). In this regard, the CRTD-Bor process applied CA-PVD Ti-deposited effects of parameters (i.e., temperatures durations) growth were examined. During boriding, Ti coating substr...

In this study, the effect of nano-TiN layer obtained by PVD method on tribological behaviour X210Cr12 (1.2080, AISI D3) cold work tool steel was investigated. Coating process carried out cathodic-arc using 200 V voltage, 350 °C temperature, 4x10-4 mbar pressure, and 50 A current application conditions. The characterization coating FESEM SEM-EDS analysis. coated uncoated samples were subjected t...

Chopping of current and induction of high voltage spikes has been observed at the rising edge of cathodic vacuum arcs. It is argued that current chopping at the rising edge is similar to the current chopping effect that is well-know for the arc current approaching current-zero. Current chopping can generate high voltage spikes, and thus cathodic arc equipment should be protected against voltage...

ii The cover image is based on a photograph of arc spots moving on the surface of a Ti cathode, taken during the first experimental session in our new PVD research system, Hydra. The explosive plasma generation in the arc spots is central to the cathodic arc deposition technique, studied and used extensively for synthesis in the Thesis. Abstract This Thesis explores the arc deposition process a...

The addition of properly selected elements, coupled in nanoscale multilayer structures can further enhance the properties of TiAlN coatings and bring new high performance. The incorporation of Y in the nanoscale pseudo-superlattice TiAlCrN/TiAlYN with typical period of 1.7 nm not only improves the oxidation resistance but also effectively reduces the coefficient of friction of the coating from ...
