Abstract

Pitting is a type of fatigue wear of the material subjected to cyclic loading, especially occurring in the gears or bearings. Si-DLC coatings are currently used due to their excellent properties such as low friction coefficient, high hardness, and wear resistance. Tribological studies of 30CrMoV9 steel samples with Si-DLC coating were performed using four ball testing machine T03 used for surface fatigue resistant test condition. Analysis of pitting cracks was performed using a profilometer, light microscopy, and scanning electron microscopy. The experimental results were compared with the theoretical model.
