摘要
通过改变稀土的加入量 ,对其在 2 0CrMnTi钢固体渗碳中的作用进行了研究 结果表明 ,适量的稀土可以显著提高渗碳效果 。
The effect of rare earth element on solid carburization was investigated through adding rare earth elements to the steel in different amount.The experimental results show that the catalytic action of proper RE elements is obvious,which can improve the structure of carburing layer and increase the hardness and wearability.
