Abstract

Stamping of Ultra/Advanced High Strength Steel (U/AHSS) sheets results in high contact stresses and non-uniform strains. These, in turn, cause high wear rates and springback. In order to prevent the excessive wear effect in stamping dies, various countermeasures have been proposed such as alternative coatings, modified surface enhancements in addition to the use of newer die materials including cast, cold work tool, powder metallurgical tool steels. A new, slider type of test system was developed to replicate the actual stamping conditions including the contact pressure state, sliding velocity level and continuous and fresh contact pairs (blank-die surfaces). A vertical machining centre, with vertical and normal force sensors mounted on its spindle, was employed to generate the contact pressure and controlled movement of die samples on sheet blank. Several alternative die materials in coated or uncoated conditions were tested against different AHSS and stainless steel blanks under certain load, sliding velocity, and lubrication circumstances. This paper briefly describes the test system and experimental methodology; and presents wear resistance performance of four different substrate materials namely DC 53, SKD 11, DRM 3, DRM 51 coated with same thermal diffusion (TD) technique. All the die samples were tested against a type of advanced high strength steel (AHSS) which is dual-phase (DP) 600 (UTS is 600 MPa).
