The Role of SiO2 Gas in the Operation of Anti-Corrosion Coating Produced by PVD

Abstract

This study examined theSiO 2 gas present in the coatings used in corrosion industry.These layers have been created by physical vapor deposition (PVD), with an appropriate performance. Sublimation of SiO 2 is used to protect PVD aluminum flakes from water corrosionand to generate highly porous SiO 2 flakes with holes in the nanometer range. SiOx/Al/SiOx sandwiches were made as well as Ag loaded porous SiO 2 as antimicrobial filler.
