Abstract

Due to high thermal, mechanical and tribological loads the tool life quantity of hot forging dies compared to other manufacturing processes is relatively low. Depending on the number of forged parts the mentioned loads lead to different failure causes of the dies. In this connection wear is the main failure cause of hot forging dies. Especially in the precision forging process of gear wheels with its exacting tolerances the tool life quantity is low, which leads to often interruptions of the production process. Because wear concentrates on the near-surface die areas, these problems can be reduced by increasing the wear resistance of these areas by the Duplex PACVD-Method, which means nitriding and multi-layer coating (TiN-TiCN-TiC).
