Fabrication of Decorative Coating/Patterning of Ceramic Pigment Powder Using Vacuum Kinetic Spraying Process

Vacuum kinetic spraying (VKS) is a relatively advanced process, by which a dense film can be fabricated at room temperature. Various materials including ceramic, metal, polymer and composite can be used as the substrate and coating materials. In this research, red and blue color films were successfully fabricated on glass substrates using Co(Al, Cr)(2)O-4 and C9H13CdN2O4SSe ceramic pigment powders in a VKS system. Although the deposition behavior of each powder differed according to particle size and/or materials, it was confirmed that the brightness and transmittance of the color film could be easily changed by controlling the process parameters. Furthermore, using masking technology, design color patterns were fabricated. As a result, it is cautiously expected that the VKS process can be utilized to produce decorative coating/patterning for product design.
