What is shot blasting?

Shot peening is the name of a mechanical surface treatment process, and similar processes include sand blasting and shot peening. Shot blasting is a cold treatment process, which is divided into shot blasting cleaning and shot blasting strengthening.

As the name implies, shot blasting cleaning is to remove impurities such as oxide scale on the surface and improve the appearance quality.

Shot peening is the continuous impact of high-speed bullet flow on the surface of strengthened workpiece, which forces the following changes in the process of cyclic deformation of target surface and surface:

1, the microstructure is modified.

2. Uneven plastic deformation leads to residual compressive stress on the outer surface and residual tensile stress on the inner surface.

3. The roughness of the outer surface changes.
