Galling behavior in sheet metal forming of advanced high strength steel (AHSS) is of great concern in automobile industry. To examine the galling mechanism in sheet metal forming, Finite element analysis and U-bending test with VC coating die coated by thermo-reactive diffusion process (TRD) against DP780 sheet were carried out. The results show that scratches are firstly observed on the die radius surface, mainly distributed at 0-10°and 30-50°. As the forming number increases, the galling mechanism changes from adhesive wear to abrasive wear, accompanied by adhesive tumors and debris. The Ry increases from 0.481μm to 3.44μm for TRD coated die surface and from 0.718μm to 6.82μm for workpiece, respectively. The wear depth predicted by finite element analysis agrees with the experimental result.
