Popis:	Hot stamping is a forming process widely used in the automotive industry. Severe adhesive tool wear occurs in the hot stamping process. Hot friction draw tests are performed to investigate the influence of the coating porosity on friction and wear. No relationship is observed between the amount of coating porosity and friction. The results indicate that higher coating porosity leads to a higher amount of wear. However, the type and distribution of the intermetallics in the coating seems to be a more important factor regarding wear. A coating with very high porosity can have relatively low amount of adhesive tool wear if another distribution of phases is present.
