Abstract
Sheet-bulk metal forming processes are commonly characterized by temporally and locally varying stress conditions, likely to affect material flow during forming and therefore the geometrical accuracy of formed parts. Local modifications of friction conditions can contribute to control the flow of material and simultaneously to reduce process forces and tool wear. This chapter discusses the systematical development and evaluation of amorphous carbon coatings aiming to adapt tribological conditions and to increase wear resistance of coated forming tools. Considering requirements and boundary conditions of forming processes, especially tungsten-modified amorphous carbon coatings demonstrated their beneficial tribological-mechanical behavior in high loaded sliding contacts due to low adhesion to steel. Coating development based on design of experiments revealed wide ranges of adjustable frictional behavior and mechanical properties contributing to local tribological conditions by the application of masking techniques. The coatings proved their operational performance in application-oriented forming processes, ranging from friction tests to simulated and experimental forming operations. Multilayer strategies increased the coatings’ toughness and their resistance to wear and fatigue. These benefits, along with an additional experimentally verified sensory function for wear condition monitoring, may provide an individual and improved service life of amorphous carbon coated forming tool
