Functional Zr, α-Ta, and (α-\b{eta}) Ta thick coatings obtained by original arc-evaporator

Novel plasma-clustered deposition technique, called PVD Droplets, as well as its main principles of operation were described. New types of obtained thick, over 20 μm, functional coatings basing on Ta and Zr have been presented. Results of research in physic-chemical properties of the coating materials are listed including preliminary studies of superconductive properties. Comparative evaluation between of obtained coatings and sample CVD coating was made.

Multi-layer Ti-based Coating Obtained by Arc PVD Method

We report the obtaining and primary studies of ~ 250microns thick multi-layer Ti-based protective coating deposited at high cooling rate from substance generated by cathode arc discharge in vacuum. High adhesion to steel substrate was attained through prior Arc plasma generator cleaning and successive Ion Bombardment method. All three arc-generated fractions including mainly droplet, vapour and ions have been utilised to form the coating. Obtained coating features pore-free, least defects and high hardness which, besides N presence, supposed to result from mainly martensitic transformations occurred at the presence of Nitrogen. Two intermediate thin layers of Cu of few microns were achieved to insert within coating presumably to reduce overall elastic modulus of the material.
