- Abstract
Forging dies are exposed to high mechanical loads at the near Surface area. Thermal and chemical stresses occur additionally. Depending on the number of forged parts different kinds of damage are developing in the Surface area, which lead to failures of forging dies. Wear is with 70% the major cause of failure. In order to reduce wear, the abrasion resistance of the Surface area of forging dies has to be increased. Therefore different methods of reducing wear on forging dies were examined, like the increase of the abrasion resistance by plasma nitrating and coating with ceramic layers (TiN, TiCN, TiC, CrN). These layers are applied on the Surface by PACVD or PAPVD treatment. At the Institute of Metal Forming and Metal-Forming Machines a wear reduction by factor 3.5 compared to nitrided forging dies for forging of helical gears was achieved. This was possible by using a coating compound of 18 ceramic layers with an overall thickness of 1.8 μm. This paper deals with investigations of this multilayer compound and further research to reduce wear through an additional TiBN coating layer.
