Vacuum coating machine ion coating technology has a wide range of applications, and can also be coated with various styles of brilliant colors. This coating technology is widely used in door and window hardware, kitchen and bathroom hardware, lamps, marine supplies, jewelry, handicrafts, and other decorative products. Manufacturing. Can be plated in gold, brass, rose gold, silver white, black, smoke gray, copper, brown, purple, blue, wine red, bronze and other colors, and can provide the required color and quality according to your requirements , the technology is favored by everyone. The following Xiaobian Huicheng Vacuum will introduce the principle of ion coating technology of vacuum coating machine in detail, and hope to help you:

1. Definition
       The molecules of the evaporated substance are ionized by electron impact and then deposited on the solid surface as ions, which is called ion plating.
        Ion plating is a combination of vacuum evaporation and cathode sputtering techniques.
2. Principle
       The evaporation source is connected to the anode, and the workpiece is connected to the cathode. When a high-voltage direct current of 3 to 5,000 volts is applied, a glow discharge is generated between the evaporation source and the workpiece. Since the vacuum cover is filled with inert argon gas, part of the argon gas is ionized under the action of the discharge electric field, thereby forming a plasma dark area around the cathode workpiece. The positively charged argon ions are attracted by the negative high voltage of the cathode, and bombard the surface of the workpiece violently, causing the particles and dirt on the surface of the workpiece to be splashed and thrown out, so that the surface of the workpiece to be plated is fully cleaned by ion bombardment. Then, the AC power supply of the evaporation source is turned on, and the evaporation material particles are melted and evaporated, enter the glow discharge area and are ionized. The positively charged evaporating material ions, attracted by the cathode, rush to the workpiece together with the argon ions. When the evaporating material ions plated on the surface of the workpiece exceed the number of sputtered ions, they gradually accumulate to form a layer firmly adhered to the workpiece. coating on the workpiece surface.
3. Classification
        ①Magnetron sputtering ion plating
        ②Reactive ion plating
        ③Hollow cathode discharge ion plating
        ④ Multi-arc ion plating.
4. Features
      The ion coating technology of vacuum coating machine has good coating adhesion performance. The tensile test of the ion-plated specimen shows that when it is stretched until it is about to break, the coating still stretches plastically with the base metal, and no peeling or peeling occurs; It has strong ability, so this method is very suitable for coating inner holes, grooves and narrow seams on parts, and other difficult-to-plating parts; the coating quality is good, and the ion-plating coating has a dense structure, no pinholes, no bubbles, Uniform thickness; simplified cleaning process.
