Abstract

This paper presents the results of the microstructure studies, quality, and a number of physical and mechanical characteristics of wear-resistant layers created on the working edges of anti-cutting bars samples made of steel 45 by
electric arc and induction surfacing methods. Hardened layers of wear-resistant alloys of three different compositions were formed by electric arc surfacing on steel and cast iron bases. Powders of wear-resistant alloys on nickel and cobalt bases were used for induction surfacing. Conducted field tests have shown that the developed technology of electric arc surfacing has a positive effect, the service life of hardened parts increases. The performed experiments on induction surfacing on the working edges of anti-cutting bars using self-fluxing powders showed that the deposited layers are quite homogeneous and have a characteristic fine-meshed and dendritic structure. In this case, complete filling of the desired profile is observed, there are no pores, cracks, discontinuities and other defects.
