Shot peening is a widely used technique to enhance the durability of metallic components by introducing compressive stress to counteract internal tensions. This process effectively minimizes the likelihood of stress corrosion and increases the lifespan of the metal. Shot peening achieves this by forming a compressive residual stress layer through the impact of high-velocity shot particles. These particles can be made of glass, ceramic, or metal, depending on the application requirements. This approach is considered one of the most cost-effective ways to boost the fatigue resistance of critical parts. By altering the physical characteristics of metal components, shot peening finds applications across numerous industries, including aerospace, energy production, and heavy manufacturing. Enhancing the strength and reliability of metal parts is crucial in sectors where safety and performance are paramount. Shot peening is a meticulously controlled cold-working process. Technicians can customize the type of shot material and the intensity of the blast to suit specific projects. Although shot peening shares similarities with shot blasting and sandblasting in terms of the high-pressure application of materials, its purpose differs significantly. While shot blasting and sandblasting are primarily used for cleaning surfaces, shot peening focuses on altering the structural properties of the metal itself. When metal cools after being cast or forged, internal stresses often develop unevenly, leading to potential cracking and failure over time. Areas subjected to greater stress are more prone to fatigue and eventual breakage. Untreated metal is particularly susceptible to early fatigue due to the presence of uncompressed stress zones. These weak spots allow tensile forces to propagate, causing fractures within the material. Each area of stress concentration is referred to as a stress riser. By bombarding these regions with high-speed shot particles, the bonding between layers is reinforced, and the surrounding metal is compressed. This compression offsets the tensile forces, preventing splits and cracks from forming. The fundamental principle behind this technique is that compression counteracts tension, thus stabilizing the metal structure. Yes, shot peening can slightly reduce the surface material, though this effect is minimal. The extent of material removal depends on factors such as the hardness of the metal and the intensity of the shot stream. Fine finishing typically affects only the highest points on the surface, leaving deeper regions untouched due to their higher compressive strength. It's important to note that shot peening does not eliminate pre-existing cracks; instead, it covers them over. To guarantee the quality of finished parts, technicians must thoroughly inspect components prior to treatment to ensure only intact, undamaged pieces undergo processing.
