Application of the filler composite rods based on the B83 babbit alloy for production of the antifriction coatings by arc welding

Abstract

The tribological properties of the antifriction composite coatings produced by arc surfacing on a steel substrate were studied. It was shown that application of the composite filler rods based on the B83 babbit alloy containing submicron particles of boron and boron carbide and micron-size silicon carbide particles makes it possible to obtain a coating with 20–40% lower friction coefficients in the case of increase in the wear resistance by 20–35% as compared with the layer formed with the use of the same B83 babbit filler rods.
