Reduction of Tool Wear through Shot Peening

In industrial manufacturing processes, the functional and guidance surfaces of forming tools are exposed to high loads. An early failure of the tool leads to associated maintenance consumes additional resources and affects the production process and product quality. By surface treatment of the tool guidance surfaces in a shot peening process, the service life of the tool can be signigicantly increased. An analysis of the influence of shot-peened surfaces on the wear resistance of tool surfaces is the subject of this project. The influence of shot peening on the surface primarily induced near-to-surface compressive residual stresses, which suppresses the initiation of cracks as a result of the tool load and significantly increases the service life of the component. In addition to the influence of residual stresses, the influence of the shot peening process on the geometry, surface quality, material hardness and wear resistance are analyzed as part of the project.
