[0002] Vacuum coating refers to a method of heating metal or non-metallic materials under high vacuum conditions to evaporate and condense on the surface of the coated object (metal, semiconductor or insulator) to form a thin film. For example, vacuum aluminum plating, vacuum chromium plating, etc. There are many different processes involved in the vacuum coating process. Each process requires a different temperature.
