A comparative study for surface texture evaluation of TiAlN coatings

This paper explores the relevant 3D roughness parameters used to characterize surface texture of titanium (Ti) based coatings. The main objective of this study was to compare the surface texture parameters, and to obtain 3D topographies of surface roughness. The applied surface analysis in areal manner allows a more complete evaluation of the component part surface and coating properties. This comparative study identified the areas for further consideration.
