Abstract

The paper presents a research about the influence of nitrocarburizing on welded coating layers. The research was made with four types of electrodes for welding coating layers. Evaluation of results was made studying microhardness and microstructure. Results reveal a good effect of nitrocarburizing in case of coating with low carbon and chrome electrodes..
