摘要

Abstract—The structure and properties of SnSbCu–Al(Bi) composite coatings formed on a steel substrate by arc surfacing with a tungsten electrode in an inert gas are studied. Extrusion-made rods based on a B83 alloy containing 3 wt % Al(Bi) reinforcing particles with a size of no more 100 μm are tested as filler materials. SnSb crystals in the composite coatings have been shown to change their morphology and to be smaller in size compared to B83 alloy coatings. The tribological properties (friction coefficient, wear rate, friction stability coefficient) of the composite coatings are superior to those of a B83 antifriction matrix alloy.
