The scope of this work was the development of a methodology for the prediction of adhesive wear on tools used for direct hot stamping. The relevant process parameters blank temperature and contact pressure were investigated with respect to the heat treatment of the blank. Their impact on adhesive layer build-up was transferred into a formulation to calculate wear height. A focus of this work lay on the identification of deterioration of the investigated pre-coating of the semi-finished product. This behavior has major impact on the adhesive layer build-up. The utilization of this developed formulation provides an adequate qualitative accordance of adhesive wear, which develops on tools used for direct hot stamping. This formulation can be used as basis and be enhanced to include different tool materials to identify the tool areas with the highest wear load.
