Improvement in Babbit Sliding Bearing Quality with Electrospark Alloying

Аннотация

Methods are considered for improving the quality of babbit sliding bearings by applying individual elements to their surface with electrospark alloying of soft antifriction metals. Numerical values are determined for the adhesion force between metals during formation of an antifriction layer using traditional (Fe–Sn) and suggested technology (Fe–Cu and Fe–Cu–Sn). The expediency of using an intermediate copper layer for improving sliding bearing running in is confirmed by calculation.
