Formulation and testing of optimised coating properties with regard to tribological performance in cold forging and fine blanking applications

摘要: Within the scope of a more environmentally friendly production, there is trend to reduce amount additives in lubricants for fine blanking, as well abolish workpiece pretreatment cold forging applications. The tribological functions or are intended be taken over by hard ceramic CVD PVD coatings, applied surface tool elements. Many applications coatings on tools metal forming known. However, every successful case appears based trial-and-error way development. Therefore, this paper will present results characterisation conditions and blanking processes. calculated using an approach four different scales. Having analysed that subjected processes, models description frictional wear processes presented. This leads formulation optimised desirable properties After coating properties, measurement these discussed.
