Abstract. The paper is concerned with determining the influence of the laser treatment process on the properties of electro spark coatings. The properties were assessed after laser treatment by analysing the microstructure, measuring the microhardness and friction coefficient. The tests were carried out for Mo and Cu coatings (the anode) electro-spark deposited over the C45 steel substrate (the cathode) and molten with a laser beam. The coatings were deposited by means of an ELFA-541. The laser treatment was performed with an Nd:YAG, BLS 720 laser. The coatings are desirable in sliding friction pairs.
