The surface damage behaviors of different galvanized steel sheets were investigated under the condition of tension-bending. The U-channel forming tests were performed for HDGI (hot-dip galvanized) and HDGA (hot-dip galvannealed) steels. Experimental results indicate that HDGI steel shows better damage resistance than HDGA steel in sheet metal forming. Scratching is the main surface damage in the forming of HDGI steel while exfoliating and scratching of coating are two types of surface damage for HDGA steel. And tool hardness and surface topography have crucial effects on part surface damage in the forming of the two kinds of galvanized steels. Different surface treatments should be applied to the forming tools in the forming of HDGI and HDGA steels for better surface qualities of products.
