稀土对化学热处理催渗作用的机理探讨

DISCUSSION ON THE CATALYTIC MECHANISM OF RARE EARTHS IN CHEMICAL HEAT TREATMENT

通过对稀土在渗剂中和在钢中作用的不同研究结果 ,探讨了稀土对化学热处理催渗作用的机理 ,并认为稀土影响渗层的原因之一在于形成了稀土周围含碳。

The catalytic mechanism of rare earths in chemicl heat treatment was probed through comparing the effects of rare earths is infiltrant on steel.One of the mechanisms of rare earths on case layer was attributed to atomic clusters around the rare earth atoms.
