Within the scope of this work the basis for an objective wear characterization of coated cold forging tools is provided. Focus was a newly developed, application related wear test and a specifically for wear characterization developed approach for evaluation of tool surfaces. The evaluation method allows the determination of dominant wear mechanisms and a quantification of wear amount. On the basis of wear characterization an objective comparison of wear behavior of coated tool surfaces, and thus a load adjusted application of coatings is possible. Attained enhancement of tool life provides a considerable potential for reduction of tool costs in cold forging companies.
