Аннотация
Based on an analysis of changes in the structure of cast babbitt of grade B83 in the process of wear tests and on a comparison of the wear curves of cast babbitt and electroplated coating of the same phase composition, there is proposed a wear mechanism at the running-in stage of B83, which is reduced to the spalling-off of coarse particles of the intermetallic β phase, pressing-in of the cleaved particles into the soft plastic matrix, and the formation of a fairly homogeneous coating uniformly paved by small, hard particles.
