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.

超声波场对铁铬铝涂层摩擦和氧化特性的影响

利用超声波振动辅助激光熔覆（UVALC）技术在 F/M 钢表面镀上了铁铬铝涂层。超声波场的引入完善了铁铬铝涂层的微观结构，提高了其微观硬度和氧化膜在高温下的完整性。硬度的提高导致磨损机制从氧化磨损转变为磨料磨损。在高温条件下，涂层更精细的微观结构产生了更致密的氧化层，从而改善了涂层的摩擦学特性和抗氧化性。此外，高温氧化分析表明，形成的主要氧化物是 Fe2O3 和 Cr2O3。
