Abstract: The paper analyzes the effect of the laser treatment process on the properties of electrospark alloying coatings. The properties are assessed after laser treatment by analyzing the microstructure and measuring the microhardness and friction force. The tests are carried out on a WC-Co coating (the anode) obtained by electrospark alloying over carbon steel St.45 (the cathode) and molten with a laser beam.
