Study on co-Permeation of Solid Rare Earth, Boron and Vanadium

摘要

The effect of rare earth compound of CeCl_3on the kinetic process, composition, microstructure and me- chanical properties of co-permeating of solid powder boron-vanadium (B-V) was investigated. The results indicate that the addition of CeCl_3 to permeating agent not only has obviously catalytic effect on permeating rate, which in- creases by more than 40/100, but also greatly improves the hardness and abrasion resistant of the permeating layer owing to the formation of new phase of CeFe_2 after C permeates into the layer of the part as an alloying ingredient.
