| Popis: | This paper present the selected properties of coatings produced on steel using for metal forming processes such as forging, extrusion or pressing. For the preparation of surface layers the laser cladding with powder technology was applied. The power of laser beam was equal to 550 W and feed rate was 400 mm/min. The aim of presented study was to obtain the microstructure similar to sintered carbide. Microstructure, microhardness, chemical and phase composition as well as corrosion resistance tests were carried out and analysed. It was found that the presence of WC particles in Stellite-6 matrix had a positive influence on mechanical properties, but negative impact on corrosion resistance of produced surface layers in comparison with the unreinforced coating. Using XRD phase analysis, the presence of the hard interstitial phases (WC, W2C, M7C3 and M23C6) in the matrix were confirmed. |
