In the present work we report the results of studies about the influence of Pt layers on the wear resistance of TiAL/TiALN multilayers deposited on 316L stainless steel by magnetron sputtering using targets of TiAL and Pt. Coating types investigated included TiAlN, TiAlN/TiAL, TiAlN/TiAL/Pt and duplex coatings with substrates nitrided by pulse plasma nitriding. The thickness of the Pt layers was from 50 nm to 200 nm and the period of TiALN/TiAL multilayer from 250 to 500 nm. The friction and wear tests were performed on a ball-on-flat tribometer and conducted in dry (unlubricated) conditions at room temperature. The loads used were from 2N to 10N and the oscillating frequency from 1 Hz to 5 Hz. The structure, composition and thickness of multilayers were studied by means of XRD, RBS and ellipsometry analysis. The surface topography and wore surface were studied by means of optical microscopy and profilometry. The results indicate that coefficient of friction (COF) of TIALN coatings decreased when metal layers are introduced.
