Study Of Diffusion Influence Materials Of Copper-Zinc-Steel On The Hardness And Micro Hardness Under Heat Treatment

Low melting metals like zinc used in this research to promote increasing of diffusion process with presence of pure powder of copper., this metals have good corrosion resistance in chemical and environmental conditions by making thin film to hardening surface of rod of stainless steel18/8Ni-Cr under heat treatment condition at 890c above eutectic line to reached austerity zone and under this line at 0,600c to obtained re-crystallization annealing and 400c0 at sufficient time 90min..chemical composition ,hardness ,micro-hardness ,and micro structures were investigated to track the effectiveness of diffusion zinc-copper melting in different s points.
