MECHANICAL CHARACTERISTICS OF AlTiN, TiAlN COATINGS DEPOSITED BY ARC-PVD METHOD ON SUS304 STAINLESS STEEL SUBSTRATE
The aim of the paper was to investigate the mechanical properties of AlTiN, TiAlN coatings deposited by the arc-PVD method on SUS304 stainless steel substrate. The coating's surface morphology and structure were examined using a profilometer, scanning electron microscopy, energy dispersion spectroscopy and X-ray diffraction. Adhesion of the deposited coatings was determined by the Rockwell test. The sliding wear resistance of AlTiN and TiAlN was much higher than that of the stainless steel sample. The deposition of PVD film on a stainless steel substrate reduces the coefficient of friction by 3-6 times. The sliding wear mechanism of AlTiN and TiAlN coatings was different, AlTiN - the vertices of the coating were obtused, grooved, and scratched along the wear, with less material displacement in both directions along the wear trace; TiAlN - the coating was strongly plowed, the material was worn and forced in both directions of the sliding wear trace.
