Influence of Die Material upon Formability and Galling of Hot-Dip Galvanized Steel Sheets
Stretching forming test was utilized to evaluate the influence of die material upon formability and galling of hot-dip galvanized steel sheets. SS41 and SKD11 were used as the substrate of die materials which CrN, TiN and DLC (diamond like carbon) were coated on SS41 and SKD11 substrate. It was found that die with coated materials performs better than that without coated materials in terms of formability and friction. Moreover, DLC coated die material shows the best performance on formability, friction and galling comparing to other coated materials.
