Hot stamping of Aluminium alloys is a process receiving increased interest from the automotive industry. However, during this process, galling, which has been recognized as one of the major drawbacks, limits the tool life and restricts the complexity and quality of the product. In order to improve the feasibility of this forming technology, an understanding of the mechanism of galling is necessary. The aim of the present study is to investigate the galling behaviours between AA6082 and two advanced anti-wear coatings, CrN and AlCrN. The study was conducted with pin-on-disc experiments at an elevated temperature. The main focus of the study is on the quantitatively measurement of galling and identifying the material transfer mechanisms between Aluminium and tool surface.
