Use of explosive technologies for production the sliding bearings of diesel engines

Results of researches on production the bimetallic sliding bearings for big diesel drives of locomotives, ships, diesel engines-generators etc. with application of explosive techniques - welding by explosion and detonation spraying are described. Bimetal of bearing is made by welding by explosion and consists of steel base and antifrictional layer from the alloy on the aluminium base. Antiscoring wearing layer from babbit B83 is plotted on the antifrictional layer by detonation spraying. Unlike the technology of joint proskating rinks welding by explosion allows to receive bimetal with width of the steel base of almost any width and ensures higher durability of layers connection. The detonation spraying allows to substi-tute an ecologically harmful galvanic way of drawing the wearing coverages.
