The Effect of Surface Roughness on Wear-Life of DLC Coated Silicon Disk in Dry Sliding

Article Preview

Abstract:

Dry sliding wear resistance of DLC coated silicon disk with different surface roughness has been evaluated using a ball-on-disk sliding tester. It was found that the transfer layer formed on steel ball produced a low friction regime and the formation of transfer layer was more active with increasing the substrate surface roughness. The wear life of DLC coating was increased as increasing the real area of contact.
