Abstract

Phosphorus L-edge and sulphur L-edge X-ray absorption near-edgestructure (XANES) spectroscopy has been used to characterize thechemical nature of tribochemical and thermo-oxidativelygenerated films from a sec-ZDDP antiwear agent. The chemicalstability of the films has been investigated by rubbing the filmsin base oil without ZDDP. The P L-edge XANES spectra have shownthat the thermal film and in particular the tribo-films are verystable after rubbing in the base oil for a long period of time.The wear scar measurements indicate that best results are givenif the coupon and pin is coated with a tribo-film and then rubbedin oil containing ZDDP.
