摘　　要：针对淬硬层深的感应淬火工件,经过维氏硬度HV1与洛氏硬度HRA硬度分布及硬化层深度的对比检验证明,洛氏硬度计检验结果更具有真实性和代表性。Counter to induction quenching workpiece with deeper hardened layer, both Vickers hardness（HV1） and Rockwell hardness（HRA） methods were used to comparatively detect its hardness distribution and hardening depth, it proved out that the detection results with Rockwell hardness tester were more real and representative.

关 键 词：感应淬火 硬化层深度 极限硬度 显微硬度HV1 洛氏硬度HRA
