摘　　要：对H13钢进行激光硬化与离子多元共渗复合处理,并对其渗层组织、显微硬度及摩擦磨损性能进行分析,对复合强化机理进行探究。结果表明:H13钢激光硬化与离子多元共渗复合处理后的试样硬度和耐磨性都优于单一离子多元共渗处理。Laser hardening and multi-elements plasma penetrating process were carried out on H13 steel, the penetrating microstructure, microscopic hardness and wear resistance wene analyzed, and the composite strengthening mechanism was explored. The research shows that the hardness and wear resistance of the sample after laser hardening and plasma multi-elements penetrating are higher than the sample after single plasma multi-elements penetrating.
