Sandblasting ( Sand Blasting ) treatment in metallic surface application is very common, the principle is to accelerate the abrasive particles to the metal surface impact, to rust, deburring, to oxide layer or surface preparation, it can change the metal surface finish and application status. Some effects of blasting parameter is the need to pay attention to, such as abrasives, abrasive grain, sand blasting distance, jet angle and velocity. In addition to sandblasting, Shotblast processing which is a good choice.
