Impact upon Surface Treatments to Fatigue Resistance

Surface treatments play a critical role in enhancing the fatigue resistance of materials. By modifying the surface properties, such as hardness, residual stresses, and composition, these treatments can significantly improve a material's ability to withstand continuous loading. Common surface treatments include shot peening, nitriding, and coating applications. These processes generate beneficial microstructural changes that delay crack initiation and propagation.

• Shot peening affects the surface by producing compressive residual stresses, which oppose tensile stresses during fatigue loading.
• Nitriding enhances the surface layer through transfer of nitrogen atoms, leading to increased wear resistance and fatigue life.
• Coating applications offer a protective barrier against corrosive environments and minimize surface stresses, thereby improving fatigue performance.

As a result, incorporating appropriate surface treatments into the design process can substantially enhance the fatigue resistance of components and structures, extending their service life and improving overall reliability.
