Si3N4 and SiC do not react with TCP at 110 deg C in air, the same conditions used in typical steel-bearing pretreatment processes. At higher temperatures, there is some reaction, but the films formed are chemically different from those on steel. Bearing tests indicate that the reaction product is ineffective in extending the life of a lubricated, modified thrust bearing. Thus, pretreatment is unnecessary for Si3N4 and SiC bearing parts under the same conditions as used for steel.
