THE WEAR PERFORMANCE OF DIAMOND-LIKE CARBON COATINGS IN RELATION TO COATING COMPOSITION AND FRICTION PAIR
Journal Title: Tribologia - Year 2012, Vol 243, Issue 3
Abstract
This study has been carried out to examine diamond like carbon coatings; a-C:H:W single-layer and TiN/a-C:H:W multilayer prepared on CoCrMo alloy by the PVD and PACVD technique. Information on the composition of amorphous carbon coatings is provided by Raman spectroscopy. The structure and surface topography were evaluated using a scanning electron microscope, a laser confocal microscope, and an optical profilometer. The adhesion was made using the scratch test method. The tribological investigations were conducted on a T-23 microtribometer and T-01 M tester machine, working in a ball-on-disc friction pair in technically dry friction and lubrication with Ringer's solution and a T-17 machine in pin-on-plate configuration with Ringer's solution. The research has shown that the mechanisms of wear of the friction elements are affected by the application of a TiN interlayer and the material used for friction pairs.
