Influence of Manufacturging Parameters on Microstructure, Chemical Composition, Microhardness, Corrosion and Wear Resistance of ZrC Coatings Produced on Monel®400 Using Laser Processing Technology

This paper presents the influence of production parameters and analysis ZrC coatings on Monel®400 substrate. The effects laser beam power microstructure, chemical composition, corrosion resistance selected mechanical properties such as microhardness wear were investigated. investigation consisted composite using processing pre-coatings made in paste form a nickel based alloy (Monel®400). In studies, diode with rated 3 kW was used. carried out constant scanning speed m/min three different powers: 350, 450, 550 W. It found that it is possible to nickel-copper substrate, where matrix from substrate reinforcing phase ZrC. Investigation for single multiple tracks. Based studies content decreased increased. A similar relationship all other investigated microhardness, resistance, resistance. As increases, Ni-Cu-based decreases. However, still greater than amount hard carbide phases affects coatings.
