Applications of Vacuum Technology in the Coating Industry
Vacuum coating technology has become an essential branch of vacuum applications, playing a pivotal role in industries like optics, electronics, energy development, packaging, and surface science. The primary methods used in vacuum coating include vacuum evaporation, sputtering, ion plating, beam deposition, and molecular beam epitaxy. Chemical vapor deposition (CVD) is another widely adopted technique. Key Vacuum Coating Methods Vacuum coating techniques are aimed at modifying the physical or chemical properties of a material's surface, which categorizes them under vacuum surface treatment technologies. Some of the most commonly used methods include: Vacuum Evaporation: The material to be coated is vaporized and deposited on a substrate. Sputtering: Atoms are ejected from a solid target material due to bombardment by energetic particles and then deposited as a thin film. Ion Plating: A method that combines evaporation with bombardment of the substrate by ions. Molecular Beam
