In this paper a study of hardened surface layer melting items after wire-EDM machining engraved. Experimental studies were carried out on steel specimens brand 40X13 and 40X13 brand samples subjected to plasma surface hardening on the current straight polarity with surface melting. Experimental studies were carried out on the wire and a wire EDM EcoCut. In a study conducted metallographic analysis and dyurometrichesky treated surface. The work revealed altered structures formed on hardened surfaces after electrical discharge machining. The work found that the resulting structural changes in the surface layer after EDM minor and do not affect the performance of the finished part. The results of microhardness of the surface layer blanks before and after electrical discharge machining.
