Study of structure and properties of B83 babbit-based antifriction materials
Comparative studies of samples of the cast B83 babbit alloy and composite materials based on it produced by powder metallurgy techniques along with coatings obtained from them by arc surfacing are performed. It is shown that the wear intensity of the cast babbit alloy is considerably higher than that of materials obtained by hot pressing and arc surfacing, which is governed by refi nement of the SnSb and Cu3Sn intermetallic phases upon fabrication, as well as by reinforcement of the babbit alloy by high-strength SiC particles.
