... tin bronzes appear to be the workhorses in bearing and bushing applications. These alloys mainly derive their strength and hardness from tin while lead, being present as insoluble, soft second phase in the microstructure, provides good antifrictional properties. These alloys may also contain zinc...

... of fretting wear, with an emphasis on steel, are reviewed in this article. This review is followed by several examples of failures related to fretting wear. Common sites for fretting are in joints that are bolted, keyed, pinned, press fitted, or riveted; in oscillating bearings, splines, and press fits...
