This process specification is for the application of enamel (porcelain) coating, primarily for use on sheet steel baffles for Advanced LIGO. It includes material requirements and the process and preparation for applying porcelain onto the baffle. These baffles are for use in an Ultra-High Vacuum (UHV) system. Porcelain is also applied to 304 stainless steel machined parts.
