CUSCINETTO A STRISCIAMENTO SENZA PIOMBO E METODO PER LA SUA FABBRICAZIONE

摘要

A lead-free plain bearing is formed by dispersing an alloy powder formed from 7-13 mass percent of Sn, 0.1-5 mass percent of Ag, and Cu on a backing, such as a steel plate, and sintering. The alloy powder may further include one or more of 0.05-0.5 mass percent of molybdenum disulfide powder and 0.1-2 mass percent of graphite powder. The bearing surface may be rough finished by machining to a roughness of 0.3-1 mum Ra and then fine finished by polishing to a roughness of at most 0.1 muRa.
