Abstract
The elemental composition and valence state of the elements and their changes with the variation of depth were investigated by mains of XPS. The result showed that there were B2O3 and iron oxide on the worn surface, and B2O3 and iron oxide contant decreased with the imcreasse in depth. It was revealed that oxidation was a charactedstic wear.
