Thickness of Transition Layer Effect on Bonding Strength in DLC Film

Yan Wu, Jie Zhao, Yan-feng Li

Abstract


Make use of PVD technology and ICS-04 ARC PRO coating equipment to prepare three groups of Cr/DLC composite films with different thickness of Cr transition layer based on Hss. Three groups of specimens in the Cr deposition time respectively for 10 mins, 20 mins and 30 mins. After measuring instrument with nondestructive testing, the film’s thickness of three groups of specimens are 0.7μm, 0.8μm and 0.9μm respectively. Measured the bonding strength of three groups of films by indentation method. The results show that the thickness of the film increases linearly with deposition time. The bonding properties improved with the increase of film’s thickness.
