研究 HT30 0激光相变硬化时的工艺参数 ,结果表明对 HT30 0链轮进行激光强化处理较表面感应淬火工艺简单 ,硬度测试及耐磨性能均可满足链轮的工作要求
The process parameters of laser quenching of HT30 0 were studied. The results show that laser quenching of HT30 0 sprocket is easier than that of surface induction quenching, hardness testing and wear resistance can meet the working requirements of sprocket
