Abrasive Media Blasting
Definition - What does Abrasive Media Blasting mean?
Abrasive media blasting is a material removal process that is used to clean substrates. Abrasive materials are propelled towards and collided with a substrate material through the use of a compressed fluid (often air or water). When the abrasive materials contact the substrate, they erode away unwanted materials.
Abrasive media blasting is an excellent method for cleaning surfaces that are heavily coated in contaminants, oil and dirt, or simply have a slightly oxidized surface. Depending on the surface's condition and the material type being blasted, different types of abrasives will be required. Either way, abrasive media blasting is a good choice for preparing a substrate.
Corrosionpedia explains Abrasive Media Blasting
Abrasive media blasting is often used to prepare a surface prior to coating, because if a coating is applied to a dirty surface or a surface that has high amounts of oxidation, then the coating could fail prematurely or corrosion may form underneath the coating. Abrasive media blasting can prevent this by removing contaminants and by providing a smooth, clean surface for the coating to adhere to so that it does not flake, crack, blister or otherwise fall off of the material's surface.
