EXPERIMENTAL INVESTIGATIONS OF THE Cu-Mo AND Cu-Ti ELECTRO-SPARK COATINGS MODIFIED BY LASER BEAM
نویسنده
چکیده
The paper is concerned with determining the influence of the laser treatment process on the properties of electro-spark deposited coatings. The properties were assessed by analyzing the coating microstructure, microhardness, residual stresses and corrosion resistance. The tests were conducted for Mo, Ti 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, BLS 720 system. The coatings, whether lasertreated or not, exhibit very good performance properties, and this makes them suitable for use in sliding friction pairs.
