摘　　要：通过激光淬火表面强化技术,在CrNiMo钢表面形成马氏体相变的表面强化薄层。采用小电流累积烧蚀方法分解了材料烧蚀过程;对比分析相同烧蚀条件下CrNiMo钢在激光处理与未经激光处理的表面烧蚀形貌及其烧蚀质量差。结果表明:激光淬火确实能提高材料的抗烧蚀性能。The thin strengthening layer on the CrNiMo steel surface was prepared by laser surface hardening. The ablation process of the steel was decomposed by the method of accumulated ablation with low current. The ablation surface and mass difference of the original steel and the steel irradiated by laser were analyzed. The results show that the CrNiMo steel through laser guenching indeed promotes the anti-ablation properties of the material.
