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...

Curved magnetic filters are often used for the removal of macroparticles from cathodic arc plasmas. This study addresses the need to further reduce losses and improving plasma throughput. The central figure of merit is the system coefficient, κ , defined as filtered ion current normalized by the plasma-producing arc current. The coefficient κ is investigated as a function of continuous and puls...

The challenge of enhancing cutting tool life has been dealt with by many research studies. However, this seems endless growing technological advancement which brings about incremental improvement in life. objective review paper is focused at assessing filtered cathodic vacuum arc deposition techniques applied on tools and their effect efficiency. particularly picks (FCVAD) among other well-iden...

Owing to their combination of high hardness and increased fracture toughness, CrTaN coatings have recently gained increasing interest as suitable candidates for metal cutting applications. However, up now, the detailed mechanisms underlying oxidation this promising coating system are not thoroughly understood. Thus within work, evolution microstructure phase composition a cathodic arc evaporate...

The filtered cathodic vacuum arc technique was employed to deposit magnetic films such as FeNi on silicon substrate. Using the normal cathode design, tetrahedral amorphous carbon and metals films can be deposited. If a magnetic target is used, the arc spot always preferably moves to the edge of the target and then extinguishes. Therefore, the arc is not stable and no film can be deposited. A ca...

High entropy alloy nitrides (AlCrTiV)N coatings were deposited by cathodic arc evaporation at various deposition bias and temperature. The mechanical properties of the as-deposited their oxidation resistance after annealing temperatures analysed. X-ray analyses show in all a FCC structure with (111) preferred orientation up to 750 °C. Up 600 °C, no oxygen penetration is measured films while 800...

This paper deals with the urgent issue of the search of new drugs based on plant raw materials that have an influence on various stages of oxidation processes occurring in the human body. The aim of this paper is to determine the antioxidant activity of the bilberry extracts that are used in the medicine practice by a cathodic voltammetry method. We consider the influence of water and alcohol b...
