Abstract
The aim of the study was to determine the influence of the lase r processing on the properties of electro-spark coatings. The properties were assessed by analyzing the coating microstructure, X-ray radiation, microhardness, corrosion resistance, porosity and tribological tests. In addition, the paper presents the res ults of measurements and analysis of electrical pulse during ESD. The tests were carried out on WC-C u coating (the anode) obtained by electro spark deposition over carbon steel C45 (the cathode) and molten with a laser bea m. The coatings were deposited by means of the EIL-8A and they were laser treated with the Nd:YAG. The tests show that the laser-treated electro-spark deposited WC-Cu coatings are characterized by lower hardness and friction force, higher seizure resistance, roughness. The laser treatment process causes the homogenization of the chemical composition, the stru cture refinement and the healing of microcracks and pores of the electro-spark deposited coatings. Laser treated electrospark deposited coatings are likely to be applied in sliding friction pairs and as protective coatings.
