  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.
