A continuous and compact Zr-alloyed layer with good metallurgical bonding was prepared on0Cr18Ni9 Ti austenite stainless steel substrate surface by double-glow plasma surface alloying technology,and the kinetics of double-glow plasma Zr surface alloying at 1 060 ℃ was studied.The results show that,increasing the distance from the Zr-alloyed layer surface,the Zr element content exhibited a graded decrease trend and the diffusion coefficient decreased gradually,while diffusion activation energy increased gradually.Vacancy density of the Zralloyed layer surface was approximately 2.945×(1012-1013)cm-2,which increased 1to 2orders of magnitude comparing with that by conventional surface alloying technology at same temperature.
