Abstract
FeCrAl coatings were applied to the surface of F/M steel using ultrasonic vibration-assisted laser cladding (UVALC) technique. The introduction of an ultrasonic field refined the microstructure of the FeCrAl coating, enhancing its microhardness and the integrity of the oxide film at elevated temperatures. The increased hardness led to a shift in the wear mechanism from oxidation wear to abrasive wear. In high-temperature conditions, a finer microstructure of the coating resulted in a denser oxide layer, improving the tribological properties and oxidation resistance of the coating. Furthermore, high-temperature oxidation analysis revealed that the predominant oxides formed were Fe2O3 and Cr2O3.
