堆焊层中球状碳化物形成机理的研究

A STUDY ON THE FORMATION MECHANISM OF THE SPHERE CARBIDE IN THE SURFACING LAYER

通过同时加入球化剂和碳化物形成元素，成功地在堆焊层中形成了球状碳化物，并对这种碳化物的形成过程进行了理论上的探讨。

In this paper, the sphere carbide was successfully formed in the surfacing layer by the addition of Ca. RE and Mo. W, andhe formation mechanism of this type of carbide was researched too.
