For successful PVD and CVD coating, surface preparation is essential. Controlled wet blasting, especially the Vapormatt process, is generally acknowledged as the best preparation technique for achieving the high levels of surface activation that are required for good coating adhesion.
The Vapormatt process employs a non-hazardous abrasive/water slurry delivered under pressure to degrease and clean the surfaces to very high standards without the need for any subsequent processing. In practice, the surface condition created by the process has been found to be far superior to that produced by conventional methods of dry sand blasting and ultrasonic cleaning.
