ABSTRACT:
A method for reducing the coefficient of friction and wear at the interface of two ceramic surfaces at temperatures above approximately 600.degree. F. The method comprising the steps of: a) providing a first and second ceramic surface; b) providing a lubricant selected from the group consisting of p-dodecylphenol, C26 and organophosphorus compounds; and c) applying the lubricant to the interface of the first and second ceramic surfaces at temperatures above approximately 600.degree. F. to reduce the coefficient of friction at the interface.
