Impact of Surface Treatments on Fatigue Resistance
Surface treatments play a critical role in enhancing the fatigue resistance of materials. Via changing the surface properties, such as hardness, residual stresses, and composition, these treatments can significantly improve a material's ability to withstand cyclic loading. Common surface treatments include shot peening, nitriding, and coating applications. These processes induce beneficial microstructural changes that prevent crack initiation and propagation.
- Shot peening affects the surface by generating compressive residual stresses, which resist tensile stresses during fatigue loading.
- Nitriding strengthens the surface layer through transfer of nitrogen atoms, leading to increased wear resistance and fatigue life.
- Coating applications provide a protective barrier against corrosive environments and decrease surface stresses, thereby improving fatigue performance.
Consequently, incorporating appropriate surface treatments into the design process can materially enhance the fatigue resistance of components and structures, extending their service life and improving overall reliability.
