【摘要】 研究了激光表面强化对 2 0CrMo低合金结构钢组织和性能的影响。结果表明经激光相变硬化处理后 ,其表硬度可达5 0 0～ 5 80HV0 .1,满足该钢用于一般零件 (链轮、齿轮、轴等 )的局部表面硬度、耐磨性等机械性能的要求 ,为改进零件表面处理方法提供了依据更多还原

【Abstract】 The effect of laser surface hardening on microstructure and properties of alloy structural steel 20CrMo was studied,in this paper.The experimental results have shown that the hardness(500-580HV 0.1 ) were obtained and satisfactoried the mechanical properties required for local hardness?wearability?strength of general components(chain wheel?gear?shaft etc.)used 20CrMo,and the results also could provide a basis for improving the surface properties of components更多还原
