研究了40CrNiMoA钢激光淬火层的组织、耐磨性及磨损机理。试验结果表明：激光淬火组织具有良好的耐磨性．比高频淬火提高了2．3倍。

The microstructure, wear resistance and wear mechanism of laser quenched 40CrNiMoA steel were studied. The experimental results show that the laser quenched structure has good wear resistance. Than the high-frequency hardening increased by 2.3 times.
