本文研究了稀土对盐浴渗钒工艺及渗层组织性能的影响，研究结果表明，稀土能明显提高渗钒速度，细化渗钒层晶粒，降低渗层的脆性。
In this paper, the effects of rare earth on the vanadizing process and the microstructure and properties of the infiltrated layer were studied. The results show that the rare earth can obviously increase the vanadizing rate, refine the grains of the vanaduided layer and reduce the brittleness of the infiltrated layer.
