The mechanical removal of PVD layers is carried out mainly by sandblasting. Aluminum oxide (corundum) is used as the abrasive medium. The mechanical decoating is advantageous especially in the case of large inner covers of the coating device. It can also be used to remove coatings from jigs and fixative components that do not have high requirements for preventing destruction, maintaining external dimensions after the sandblasting and particularly on the roughness of the formed surface. The ability to remove any coating regardless of its chemical composition or structure is the advantage of mechanical decoating.
