Abstract

A technique has been developed, whereby mechanical strength and excellent oxidation resistance is imparted to self-lubricating bodies of high lubricant content. By an “amalgamation” of powdered solid lubricants, such as tungsten diselenide, with a gallium alloy, followed by a subsequent compression-curing cycle, self-lubricating surfaces have been formed that resist oxidation at a temperature of 1500 F. This paper presents friction-wear characteristics of these materials at temperatures to 950 F. They offer potential as load-bearing surfaces and seals in high temperature applications for both oxidizing and inert or vacuum environment. Presented as an American Society of Lubrication Engineers paper at the Lubrication Conference held in Minneapolis, Minnesota, October 18–20, 1966.
