Additive effects on boundary film formation: Depth profile by Auger electron spectroscopy - (PPT)

摘要

Boundary film thickness as well as relative distribution of compounds constituting the film impacts wear/friction properties. Film thickness estimate is in close agreement with published data using complementary techniques. Presented data generated on insoluble, solvent washed boundary film. Literature reports - For boundary films, the friction and wear was not correlated to their tangential elastic properties, but were more likely to depend on the different microstructures of the film. Mild wear primarily lead to phosphate formation whereas extreme pressure conditions will favor the growth of sulfides. For phosphate films excellent wear resistance was seen at contact pressure up to 1 GPa.
