Study on Diffusion Bonding of Stainless Steel to Mild Steel
초록
Cladding of stainless steel on mild steel was prepared by diffusion bonding process. The bond strength increased with an increase of bonding temperature and time. It was also found that the bond strength increased as the surface roughness decreased. After the diffusion bonding of stainless steel-mild steel, the mild steel part near the bonded interface showed higher strength than the base steel due to the migration of chromium and nickel from stainless steel to mild steel. Carbon migration from mild steel gave effect on the formation of chromium carbides at grain boundaries of stainless steel, the fractograpohic features of the imperfectly bonded interface showed rather coarse dimples in the mild steel part and very fine dimples in the stainless steel part.
