Shot peening is a widely used surface treatment to improve the static and cyclical strength of metal components. It is utilized in the mechanical stabilization of edge layers and for incorporation of more advantageous residual stresses. Shot peening is generally viewed as detrimental regarding brittle materials and is therefore not utilized. Experience has shown that in room temperature, brittle materials such as ceramic break as opposed to deforming. Experiments on brittle ceramic materials carried out at the Fraunhofer IWM have shown that under precise boundary conditions shot peening can yield high compressive residual stress to over 2 GPa. This allows for drastic improvements to near surface strength characteristics in ceramic, hard metal and hard-chrome layer components, as well as warp balancing and thin-walled parts to be formed without cutting.
