Microstructure and Wear Properties of a Novel Mixed Stellite Coating Deposited on H13 Steel Using Laser Cladding Technology
In this study, a novel mixed stellite coating made from the 30% Stellite 3 and 70% Stellite 21 is deposited on H13 alloy using laser cladding technology, aiming at improving the micro-hardness and wear properties compared to Stellite 21. The microstructures of the mixed Stellite coating and Stellite 21 coating are examined using optical microscopy, scanning electron microscopy, and energy-dispersive spectrometer. The wear resistance of both Stellite coatings is evaluated by dry sliding wear test method. The results demonstrate that the Stellite 21 coating is composed of γ-Co, Co3Mo interdendritic phase and M23C6 carbide, while the mixed Stellite coating is only composed of γ-Co and M7C3 carbide-enriched W and Mo. The mixed Stellite coating exhibits superior micro-hardness and wear properties compared to the Stellite 21 coating.
