The GTAW method was employed for surface remelting of copper ductile cast iron of 0.48 or 0.95 % copper content by mass and pearlitic/ferritic or pearlitic structure. The cold remelting or multiple remelting technique was adopted to harden the cast iron. The remelted layers underwent tests of hardness, tests of micro-hardness of individual structural components and microscopic tests (LEM). The tests focused on the presence of macro- and micro-cracks within the hardened layer.
