摘要
对12CrNi3A钢进行了渗碳激光强化复合处理研究。利用扫描电镜和磨损试验机对其微观组织和磨损性能 进行了较细致的分析。结果表明,12CrNi3A钢在复合工艺作用下,随着表面硬化区层深的变化,其组织结构发生明显变 化;随着激光扫描速度的增加,硬化区硬度和耐磨性增大。
The experiment that 12CrNi3A steels were treated by carburizing and laser transformation hardening was carried out. The microstructure and abrasion performance of the treated steel were studied in detail by SEM and abrasion tester. The results show that the microstructure obviously varies with the change of depth in laser hardened zone. With the scanning speed going up, the hardness and the wear - resisting property are improved.
