چکیده انگلیسی
The aim of this study was to investigate the effect of a coating's crack density and a post-polishing process on the friction and wear performance of hard-chrome coatings. Three different crack densities combined with a post-polishing process were tested using the ball-on-disc configuration in a poly-alpha-olefin oil (PAO) lubricated point contact. The results clearly show that for hard-chrome coatings and random, non-uniform crack-type textures the size and density of the crack pattern determine the friction and wear performance of the contact. For the investigated contact conditions the best performance, i.e., low friction, fast running-in and minimum wear, was obtained when combining medium-density cracks of â¼3% and the post-polishing.
