Abstract In the article the results of set of experiments concerning the changes in microstructure of plasma sprayed Al2O3, Cr2O3 and W2C coatings of tribological test pieces obtained with use of locally applied laser beam treatment are given and discussed. The improvement of sprayed on coating layer adhesion to the steel base was ascertained and evaluated. The possibilities of the application of the described technology for development and production of slide elements of tribological joints are noticed.

Abstract The article presents results of research relating to the impact of laser treatment done to the surface of plasma sprayed coatings NiCrAlY. Analysis consisted microstructure and oxidation resistance of coatings subjected to two different laser melting surfaces. The test were performed at a temperature 1000°C the samples were removed from the furnace after 25, 300, 500, 750 and 1000 hours. The investigations range included analysis of top surface of coatings by XRD characterization oxides formed types and microscopic investigations of coatings morphology
