Surface treatment processes: the differences between polishing, shot blasting, sandblasting, shot peening, and powder coating.

In the field of materials science and engineering, surface treatment is a crucial technology that not only improves the appearance of materials but also enhances their physical and chemical properties. Polishing, shot blasting, sandblasting, shot peening, and powder coating are five common surface treatment techniques. Although their purpose is to improve the material surface, their principles and applications vary significantly. This article will provide an in-depth comparison and discussion of these five techniques from the aspects of definition, principle, application, and advantages and disadvantages.
