The influence factors and the kinetic conditions of the Re B V co permeation by pasty agent were studied. It is shown that the Re elements in the pasty agent have obvious catalytic effects on the permeation under suitable technical conditions; KBF 4 has an important effect on the permeation of the activated atoms. The formation of the permeated layer was analyzed both theoretically and experimentally, and based on the analysis, the mechanism of the Re B V co permeation was revealed.
