Everyday decorations we bring are coated with a layer of film, such as rings, earrings, necklaces, and decorations applied to other products, all of which have been coated with a layer of film by a jewelry pvd coating machine. in order to achieve the desired effect and performance. For those who are not very familiar with the vacuum industry, especially those who have little contact with the jewelry pvd coating machine, there will be some doubts. What are the specific advantages of the jewelry pvd coating machine coating? The following Xiaobian Huicheng Vacuum will introduce the advantages of jewelry pvd coating machine coating in detail, and hope to help you:

       Jewelry vibration electroplating is vacuum coated by sputtering. Due to the different coating methods, the effect of the film prepared by the same coating material will also be different. Although it cannot be seen by the naked eye, it does have certain advantages. The film thickness stability is good. Since the thickness of the sputtering coating film has a great relationship with the target current and discharge current, the higher the current, the greater the sputtering efficiency. Because as long as the current value is well controlled, how thick or thin the film needs to be plated is fine.
       The film layer has strong bonding force. During the vacuum plating process, some electrons hit the surface of the substrate, activate the surface atoms, and produce a cleaning effect, and the energy obtained by the sputtering of the coating material is higher than that obtained by evaporation. 1 to 2 orders of magnitude, when the coating atoms with such high energy hit the surface of the substrate, there is more energy that can be transferred to the substrate, generating more thermal energy, accelerating the movement of the atoms activated by electrons, and Part of the coating material atoms are fused with each other earlier, and other coating material atoms are deposited one after another to form a film, which strengthens the bonding force between the film layer and the substrate.
      A wide range of coating materials, because the sputtering coating is sputtered by the high-speed bombardment of argon ions, of course, the thickness is within the allowable range, and the current is well controlled, no matter how many times the coating is repeated, the film thickness is No change, the stability of the film thickness can be attributed to the good controllability and repeatability of the film thickness. Unlike metal electroplating processing, which is limited to the use of plating materials with a relatively low melting point due to the melting point, sputtering coating solid substances can be used as plating materials.
      The application of jewelry pvd coating machine is very common. Now the quality of life is gradually improving, and the requirements of natural people's decorations are also constantly increasing. Then the coating technology of jewelry true coating machine must also be continuously innovated and reformed.
