Sintered bearing alloy for high-temprature application and method of manufacturng an article of the alloy

摘要

A sintered bearing alloy for high-temperature application containing from more than 5 to 10 weight percent h-BN particles having a size of 100 to 500 mu m, which are dispersed in the matrix of stainless steel. Granulated h-BN powder is mixed with austenitic stainless steel powder and the resultant blended powder is formed into a green compact by compression, after which the green compact is sintered.
