Unlike cutting tools, most shaping tools are still uncoated. The main reason for this is the larger sizes and complex shapes of the tools, which can make it challenging to ensure good adhesion between the substrate and the PVD coating. Nevertheless, in recent times, coating methods and types of coatings with excellent tribological properties have been established, which significantly improve the adhesion (forming of aluminum alloys and stainless steel) and abrasion (high-strength steels) wear resistance of forming tools.
