Abstract [en]

The usage of the hot stamping process is of great importance due tothe high demands for production of ultra-high strength steels (UHSS).An Al-Si coating is normally applied to the steel to preventdecarburisation and scaling during heating and to improve thecorrosion resistance of the final component. During heating, the Al andthe Si from the coating combine with the Fe from the steel substrate toform hard intermetallic phases. Little is known about the influence ofthe heating conditions on the tribological behaviour of the Al-Sicoating during interaction with tool steels. The present workinvestigated different heat treatment parameters and the influencethey had on the microstructure of the coating and the gallingbehaviour. With low alloying temperatures (700C), severe gallingoccurred and increasing the alloying temperature to 900C resulted inalmost negligible material transfer. The reduction in galling wasassociated to the development of Fe2Al5 and FeAl2 at the surface.
