Abstract:

Lubrication and surface engineering plays a vital part in the efficiency of machine components. By using low friction fluids and low friction coatings the efficiency of machine components can be improved dramatically. Glycerol is an example of a fluid with extraordinary low friction characteristics in various systems. Diamond like carbon (DLC) coatings have also been shown to reduce friction in a variety of tribological interfaces. In this study, the elastohydrodynamic performance of glycerol with DLC coated surfaces has been investigated in rolling sliding contacts at high pressures and high slide-to-roll ratios. The DLC-glycerol system is compared to a steel-synthetic oil system and the differences are significant.
