Shot Peening 101: A Look at the Process

Metal is one of the most durable materials on the planet. It’s no wonder why many use it in different industries for various purposes. For fields that require the strength and durability of metals at the maximum level, however, knowing how to enhance metal’s durability and finish is necessary.

One of the ways to improve finishes of metal and ceramic materials is through shot peening. Know more about the process in this guide:

What is shot peening?

The goal of shot peening is to prevent fatigue and stress corrosion failures, so you can prolong the lifespan of the product. The process is done by using small spherical shots to blast the surface of the parts to be finished. Imagine a hammer dimpling a surface, but on a smaller scale. This cold work process is continued until overlapping dimples are made throughout the surface that is being treated.

How does it strengthen the surface? The compression strengthens the metal, making it resistant to fatigue, corrosion, and cracking. Shot peening can also be performed on ceramic surfaces.

Shot Peen Forming

Unlike shot peening that aims to strengthen the surface of the metal, shot peen forming’s goal is to extend the superficial layer of the component.

Correction of Distortion

Often referred to as the reverse of shot peen forming, the goal of this process is to compress the treated areas to achieve a completely flat surface after it has undergone the process of heating or machining.

There are other ways to strengthen metals and shot peening is one of them. Understanding how the process works allow one to further understand its usage and importance in various industries. Do you have a material that needs such finishing? Maybe shot peening is the process that you have long been looking for.
