摘 要：The effect of RE elements on nitrocarburizing kinetics of 35CrMo steel was studied. The results show that adding proper quantity of RE can decrease the diffusion activation energy of N atoms, the nitrocarburizing process is accelerated obviously under the acting of activity and catalysis of RE, and compared with nitrocarburizing process without RE addition, the nitrocarburizing rate increases 25%～30%. In addition, the math formula was set up between case depth of the samples and its corresponded nitrocarburizing time, and the catalytic effect mechanism was also preliminarily discussed.
