Tribology of nonmetals

It is assumed that the present chapter will serve as a focal point for those who are concerned with the tribology of nonmetallic materials. The differences between polymeric and metallic friction are discussed regarding the discrepancy in the viscoelastic behavior of polymers and the elastic–plastic behavior of metals. The mechanisms of wear are described, and the factors affecting friction and wear of polymers are extensively explained. The fundamentals of polymeric composites tribology and how various structures and compositions can affect their friction and wear behavior are explained. The friction and wear behavior of rubber are overviewed. Comprehensive discussions on the tribology of ceramics, cermets, and graphite are also included. Tribology of diamond and diamond-like carbon (DLC) films are addressed. It is confirmed that DLCs are inherently self-lubricating and resistant to erosion, abrasive, and adhesive wear.
