- Abstract:
- This article studies the sound of rare earth, osmotic composition and tissue structure, and seepage layer performance of rare earth. By optimizing the appropriate types of rare earth, add quantity and process parameters. The results show that rare earth has obvious seepage effects, which can increase the seepage rate by 30 % compared with without rare earth; increased carbon and nitrogen content in the surface layer, increased the number of carbides, the particles became small, diffused, and extended inward distribution. Matriots and residuals are refined; the hardness of the peak layer is increased, and the microscopic hardness distribution becomes reasonable; the abrasion resistance of the penetration layer under high load is increased by about 30 %, and the life of the feed pressure of this technology has increased significantly. Electronic energy spectrum analysis and phase analysis show that rare earth elements infiltrate into the infiltration layer and form a rare earth compound phase, which plays a role in micro -alloy.
