Admiral Makarov National Shipbuilding University, Nikolaev, Ukraine

Abstract
Structural transformations in low-carbon steels during carbon-electrode arc surface hardening by heating without melting are considered. The effect of carbon, grain size and initial metal temperature on the conditions of hardening of low-carbon steels is shown.
Keywords: carbon electrode, surface treatment, low-carbon steels, hardenability, martensite
