Abstract
This study focuses on the influence of surface geometry of hard coatings on tribological behavior. TiN, TiAlN, AlTiN and nanocomposite (nc-Ti1−xAlxN)/(a-Si3N4) (nACo) coatings were deposited by means of the lateral rotating cathode arc method on high speed steel (HSS) substrates. Surface topology (area of 50 μm × 50 μm, 10 μm × 10 μm and 5 μm × 5 μm) investigations by the atomic force microscopy (AFM) revealed that for all types of coatings the non-Gaussian height distribution function (HDF) is mainly due to the macroparticles. Factors and mechanisms affecting the value of the coefficient of friction (COF) during the running-in period were discussed.
