Zinc Shot Blasting
Definition - What does Zinc Shot Blasting mean?
Zinc shot blasting is shot blast cleaning using zinc shot pellets to prepare or modify the surface.
Shot blast cleaning is a method of abrasive blast cleaning. Small metal shot acts as an abrasive media for surface preparation. Shot blast cleaning forcefully propels a high-pressure stream of abrasive material (metal shot) against a surface to:
- Smooth a rough surface.
- Shape a surface.
- Remove surface contaminants such as rust.
- Remove paints or coatings.
Zine shot blasting is also known as zinc shot cleaning.
Corrosionpedia explains Zinc Shot Blasting
Zinc coating acts as a cathodic protection barrier between a harsh corrosive environment and the metal surface and is commonly sprayed or applied as a top coat with a urethane paint or epoxy on a steel surface. The shot blasting technique is used to clean and prepare the surface for further coating applications. Zinc shot is used with this process.
Shot blast cleaning is used to:
- Clean iron, steel, non-cast parts, forgings, mechanical sheets, rods, coils and wire.
- Prepare surfaces to be painted or coated.
- For shot peening, to alter a material's mechanical properties (e.g., to increase its resistance to fatigue).
