Abstract
The paper described properties of electro-spark deposited coatings under influence of the laser treatment process. The properties
were assessed by analyzing the coating microstructure, X-ray radiation, microhardness, bonding strength, corrosion resistance,
porosity and wear tests. The tests were conducted for Mo and Cu coatings (the anode) which were electro-spark deposited over
the C45 steel substrate (the cathode) and melted with a laser beam. The coatings were deposited by means of an ELFA-541. The
laser processing was performed with an Nd:YAG laser. The coatings after laser processing are still distinguished by very good
performance properties, which make them suitable for use in sliding friction pairs.
