Abstract
The structure and mechanical properties of a bimetallic joint obtained by electric arc surfacing of high-alloy stainless steel onto carbon steel were investigated. Metallographic studies and microhardness measurements have shown that a decarburized layer is formed on the carbon steel side, a high-strength white martensitic area on the stainless-steel side, and a layer with a large proportion of the carbide component is observed directly at the fusion boundary. Subsequent heating to 950°C with a holding time of 1 hour leads to an improvement in the stress-strain state of the deposited metal, but an increase in microhardness is observed in the martensitic region near the fusion boundary. To obtain optimal characteristics, it is necessary to reduce the annealing temperature and increase its duration.
