Experimental Study on Surface Damage in Forming of Galvanized Steel Sheets

Abstract:

U-channel forming tests were performed to investigate the surface damage behavior of hot-dip galvanized (GI), galvannealed (GA) and electrogalvanized (EG) steels in sheet metal forming (SMF). Experimental results indicate that the surface topographies of galvanized steels are roughening with the number of forming in sheet metal forming (SMF) and the types and mechanisms of surface damages of the three coatings are different. And tool hardness has great effects on surface damages of the GI and GA steels while the influence of tool hardness on surface damage of EG steel is negligible.
