There are many industries in which pvd coating machine is used, and the natural coating processes are also different. The most frequent ones we contact every day are sputtering, ion plating, and vacuum evaporation. As long as the staff who have simple contact with vacuum coating equipment, they should have heard of this. There are three electroplating processes, but in fact, there are far more than these three, and more may come out in the future. The following Xiaobian Huicheng Vacuum will introduce the common coating processes of pvd coating machine to you, hoping to help you

      Vacuum electroplating is a new technology that is different from water electroplating, and it is a relatively environmentally friendly electroplating technology.

      Vacuum plating processes include vacuum evaporation, cathode sputtering, ion plating, etc.

      Vacuum evaporation:
      Vacuum evaporation is a process of heating the material under vacuum conditions, placing the film-forming material in a vacuum for evaporation or sublimation, and depositing one or more layers of film on the surface of the substrate.

      The principle is to bring the temperature to the evaporation temperature of the coating material, and transfer the generated steam from the vacuum chamber to the low-temperature parts to condense, and no oxidation will occur in a vacuum environment. Note that the materials used for vacuum evaporation should be considered. Melting and boiling points.

      Cathode base plating:
      Cathode base plating is also called magnetron sputtering. The inert gas plasma generated by glow discharge blasts the atoms of the metal target and deposits them on the substrate. The cathode base plating process requires a vacuum of 1.3*10-3Pa. . An orthogonal electromagnetic field is formed on the surface of the cathode target, and the adhesion of the base-plated film layer is stronger than that of vacuum evaporation, which is a process with high utilization rate of vacuum coating technology at present.

      Ion plating:
      Ion plating is a method of depositing on the surface of a substrate under the bombardment of gas ions or substance ions. Ion plating is a new invention of vacuum coating technology. Although the ion plating process is also implemented in a vacuum chamber, the coating process is through charge transfer. It has strong penetrability and can enter into the substrate to be plated with very strong adhesion.

      pvd coating machine Vacuum electroplating is a physical method. Coating is established in a vacuum environment. The vacuum electroplating process is a mature technology. Basically, products that require coating in various industries can use vacuum coating.
