Abstract
1. With an increase in carbon content in the steel being treated, the thickness of the alloyed layer increases and its microhardness also increases. The carbon exerts a deoxidizing action on the layer being formed and promotes a reduction in the threshold of deerosion and also additional strengthening of the layer as the result of the formation of binary η-carbides. 2. Electroerosion alloying under the investigated conditions leads to an increase in the wear resistance of carbon steels by 1.5–6.2 times, which makes it possible to recommend tungsten electrodes for electroerosion alloying of the surfaces of carbon steel parts operating under conditions of intense wear.
