摘　　要：对高压空气压缩机曲轴进行激光宽带扫描,在其表面形成相变硬化层。分析结果表明,激光淬火后的曲轴不仅表面的耐磨性、耐腐蚀性和疲劳强度有所提高,并通过工厂的试验收到较好的效果。The hardening layer was formed on surface of high-pressure air compressor＇s crank shaft by laser broadband scanning. The analysis results show that querching the surface wear resistance, corrosion-resistance and fatigue strength of the crankshaft can be improved;after laser treatment, and it is achieved good effects in factory practical test.

关 键 词：激光淬火 曲轴 耐磨性 残余应力
