为了提高高品质液压油缸的耐磨性能，使用45钢作为模拟材料，采用YLR-4000型光纤激光器在其表面进行激光熔覆，制备NiCrMn+WC复合涂层。利用金相显微镜(OM)和扫描电镜(SEM)分析其显微组织和微观形貌，利用X线衍射仪及能谱分析涂层的相结构和成分，并测量了其硬度以及磨损性能，获得最优的工艺参数。结果表明：激光熔覆层的致密度良好，无明显的孔洞出现；熔覆层硬度较基体的提高3~5倍，且在一定范围内，随着扫描速度的增加以及扫描功率的减少，熔覆层的硬度强化效果明显；硬质相的加入使其表面的耐磨性显著提高，在扫描速度为360 mm/min，功率为2.5 kW，WC含量为30%(质量分数)时，熔覆层的各项性能达到最优。
