This document specifies the method for depositing cadmium layers according to the vacuum deposition process, for use in aerospace construction. According to this process, cadmium metal is vaporized under vacuum and deposited directly on the base material with an interlayer. The coating produced in this way is ductile and electrically conductive. This document is applicable whenever referenced.
