This article presents the results of a study of the microstructure and mechanical properties of indium-alloyed tin babbitt B83. The presence of intermetallic phase particles formed during alloy crystallization was also established. The amount and size of the second-phase particles have a significant impact on the mechanical properties of the original alloy. A further increase in the alloying element concentration leads to a refinement of the structure, making it more uniform and fine-grained. Using standard hardness testing methods (the Brinell method), it was established that an increase in the hardness and strength of tin babbitt B83 is achieved with the addition of up to 1.0 wt.% indium. It is shown that the introduction of indium affects the distribution of intermetallic phases, as well as the strength and plastic properties of tin babbitt B83. The results obtained can be used in the development and improvement of antifriction materials for plain bearings.

Keywords: tin babbitt B83, indium, microstructure, mechanical properties, hardness, strength.
