The effects of processing and compositional variations on the tribological performance of PM212 were investigated. PM212 is a self lubricating powder metallurgy composite, comprised of a wear-resistant, metal-bonded chromium carbide matrix, containing the solid lubricants barium fluoride/calcium fluoride eutectic and silver. Several composites were formulated which had lubricant, matrix, and processing variations. Processing variations included sintering and hot isostatic pressing (HIPing). Pins fabricated from the composites were slid against superalloy disks in a pin-on-disk tribometer to study the tribological properties. Several composites exhibited low friction and wear in sliding against a nickel-based superalloy. The results showed that, under these test conditions, the tribological properties of PM212 are not highly sensitive to compositional and processing variations within the matrix studied. 9 refs., 6 figs., 6 tabs.
