Abstract

This Paper describes a study on the effect of oxygen on friction and wear of cobalt based alloy Stellite 6B and austenitic stainless steel SUS316 for comparison. Reciprocating sliding tests were conducted under dry conditions in nitrogen, and in nitrogen gases which contain different concentration of oxygen. The result showed that friction and wear of SUS316 and Stellite 6B were strongly affected by the oxygen concentration in nitrogen gas. At higher oxygen concentration than 1 %, the coefficient of friction and wear loss were larger than at lower oxygen concentration for both materials. Surface analysis of wear scars with X-ray Photoelectron Spectroscopy revealed that severer oxidation occurs at higher oxygen concentration, and that oxides or hydroxides are formed on the surfaces even at oxygen concentration of less than 0.1 %.
