Updating his 1994 original edition, Bayer (a Fellow of the American Society for Testing and Materials) incorporates new tribological research into this new work explaining thermal and oxidative wear mechanisms, behavior, and phenomena; discussing wear testing methodology; and detailing 20 phenomenological and 11 operational wear tests. New appendixes include tables on threshold stress for galling and sliding wear relationships for different contact situations. Also included is a glossary of wear mechanisms, related terms, and phenomena.
