Up to now, there was no proven knowledge about, which processing parameters respectively which nitrided case leads to the best life time of the tools. In the present work, the influence of nitriding and nitrocarburizing with all their variety of nitrided cases on the lifetime and wear of forging dies was investigated. Eight promising treatments were transferred to forging dies, in order to create a number of different nitrided cases. The tools were used in serial production and their lifetime was determined under real conditions. At the lifetime end, critical parts of the tools were metallographical investigated, in order to find out the wear mechanisms. Finally, a recommendation was developed which nitrided case revealed the best results for a given loading condition. |
