pvd涂层原理English:PVD coating, or physical vapor deposition coating, is a process used to deposit thin films or coatings on substrates. The principle behind PVD coating involves the use of physical processes such as evaporation, sputtering, and ion plating to create a vapor of material, which is then deposited on the surface of the substrate. During the evaporation process, the material to be coated is heated until it reaches its vapor pressure and then condenses on the substrate surface to form a thin film. In sputtering, high-energy ions are used to bombard the target material, causing atoms to be ejected and deposited on the substrate. Ion plating involves the use of ions to bombard the substrate surface and the coating material, leading to a denser and more adherent coating. The resulting PVD coating is known for its excellent adhesion, hardness, wear resistance, and chemical stability, making it suitable for a wide range of applications, including cutting tools, decorative coatings, and semiconductor devices.中文翻译:PVD涂层,即物理气相沉积涂层,是一种在基材上沉积薄膜或涂层的工艺。
