高机械、化学和热循环载荷是热锻造应用的载荷状态的特征。此外，这些载荷是同时作用的，这导致在短的工具寿命之后提供工具部件的形式发生故障。在所有原因中，磨损约占70%，是导致生产停机的主要原因。其他失效因素是热裂纹和机械裂纹，以及由于高热负荷导致硬度损失而导致的塑性变形。通过对工具进行表面修改，可以减少造成的生产停机时间。最近研究工作的不同结果证明了新开发的PVD和PECVD涂层系统在减少模具磨损方面的巨大潜力。采用PVD镀膜设备开发的CrVN涂层系统和含硼多层PECVD涂层系统在锻模上进行了应用。对发生磨损机理的基本研究表明，涂层系统必须适应与载荷和损伤相关的决定性过程。
High mechanical, chemical and thermal cyclic loads characterize the load regime of hot forging applications. Additionally these loads are acting simultaneously which leads to a failure of the form giving tool components after a short tool life. Accounting for about 70% of all causes, wear is the main reason for production downtimes. Other failure factors are thermal and mechanical cracks as well as plastic deformation as a result of the loss of hardness due to the high thermal charge. The caused production downtimes can be reduced by surface modifications of the tools. Different results of recent research works prove the high potential of newly developed PVD and PECVD coating systems regarding the reduction of die wear. CrVN coating systems developed by PVD coating equipment and boron containing multilayered PECVD coating systems were applied to forging dies. Basic investigations of the occurring wear mechanisms show the qualification of the coating systems which have to be adapted to the decisive process related loads and damages.
