Abstract:
In this paper the P-V diagram of steal/steel rubbing pair under
lubrication was measured on the ball-on-disc testing machine using the
stepwise loading method. The role of lubricating oil in various
transition regions was also examined. It had been proved that the
transition of lubrication states in the P-V diagram was constituted by
not three, but five regions. This paper analysed systematically also the
composition and valence state of surface film by AES and ESCA in
different lubrication states, discussed the role of oxide film in
transitions of P-V diagram, and proposed a model about the structure and
role of oxide film as well.
