Microstructures Associated with Wear
High strain associated with metal wear is discussed and macroscopic and fine microscopic aspects are included. Mechanisms for the production of debris which include extrusion of microfurrows, adhesive transfer, and fragmentation are outlined. The structure of near surface deformation zones, a thin transfer layer, is examined. The similarity among the size of fine wear debris particles, the structure of the transfer layer, and large wear flakes is shown. Differences in microstructure associated with dry wear and lubricated wear are pointed out. Some parallels and differences for classic high strain deformation and wear microstructures are discussed.
