A methodology based on finite element computations is proposed to predict the galling onset of aluminium alloys in cold forming. The methodology assumes that galling starts as soon as a finite element in the area of contact has reached a critical dam

Galling is an important issue in metal forming of tribologically severe materials such as high strength steel, stainless steel, Al- or Ti-alloys, since it leads to poor surface quality of the formed components, production stops and possibly deteriora

The usage of diamond-like-carbon (DLC) tool coatings has previously been found to prolong the tool life of forming tools, while reducing the demands of the lubricants used for different metal forming operations. This allows for a more environmentally
