In previous work it has been demonstrated that metals and chemically-activated ceramics can be lubricated up to 300 C by continuous application of a vapor-delivered polymeric derivative of tricresyl phosphate (TCP). These studies have been extended to include temperatures of 500 C. At higher temperatures, it was found that to obtain good lubrication, it was necessary to apply a precoat or initial film of the TCP-derived polymer. In particular, if at 400 C a precoat of 0.01 mm was applied, good lubrication was maintained up to loads of 5.4 MPa. At a temperature of 500 C, even with a precoat of 0.02 mm, high friction and wear were obtained after a critical period of time which depended on the load applied. Loads up to 5.4 MPa and sliding contact speeds of 12 cm/s were used. A model was developed to predict the thickness of the precoat necessary to prevent temperature build-up and maintain good lubrication up to a given critical time. The method should be applicable to temperatures up to 700 C for sliding contact. 7 refs.
