Abstract

The paper deals with determining the influence of the laser treatment process on the properties of electrospark alloying coatings. The properties are assessed after laser treat by analyzing the microstnicture, 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.
