Abstract
Tin bronzes are widely used in various industries to produce parts running under friction conditions. Thus, eutectoid component distribution is specified for BrO10S2N3 bronze used for critical part manufacturing. The paper studies the effect of casting and ingot solidification conditions on the distribution and amount of eutectoid in the alloy structure. Several ways of bronze die casting were tested, including ones with water cooling and without it; using ultrasonic waves and without them. As a result, we developed the method of BrO10S2N3 tin bronze casting into a combined mold subjected to ultrasonic waves. The mold is a steel casting form placed in graphite filler with an insulating insert at the top of the mold. The results showed that the new technology allows producing ingots that fully meet the requirements of regulatory documents and have a high yield exceeding 70 %.
