Wear Analysis of DLC Coating in Oil Containing Mo-DTC 2007-01-1969

Diamond-like carbon (DLC) coating has excellent properties like high hardness and low friction. So it has attracted considerable attention in recent years as a low-friction coating material. However, some DLC coatings display increased wear in oil containing Mo-DTC (Molybdenum-dithiocarbamates). Wear analyses of sliding surface after block-on-ring tests were conducted suggest that the decomposition product from Mo-DTC, MoO3, reacts with active sites in the DLC to promote the wear of DLC.
