pvd coating machine ion coating technology has a wide range of applications and can also be used to coat 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, black, smoky gray, copper, brown, purple, blue, burgundy, bronze and other colors, and can provide the required colors and quality according to your requirements , this technology is favored by everyone. Below, the editor of Huicheng Vacuum will introduce the principle of ion plating technology of pvd coating machine in detail, hoping to help you:

1.Definition
The molecules of the evaporated substance are ionized by electron collision and then deposited as ions on the solid surface, which is called ion plating.
Ion plating is a combination of vacuum evaporation and cathode sputtering technology.
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 three to five thousand volts is passed through, a glow discharge occurs between the evaporation source and the workpiece. Since the vacuum hood 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 zone around the cathode workpiece. The positively charged argon ions are attracted by the negative high voltage of the cathode and violently bombard the surface of the workpiece, causing particles and dirt on the surface of the workpiece to be splashed and thrown away, so that the surface of the workpiece to be plated is fully cleaned by ion bombardment. Subsequently, the AC power supply of the evaporation source is turned on, and the evaporation material particles melt and evaporate, enter the glow discharge area and are ionized. The positively charged evaporating material ions, attracted by the cathode, rush towards the workpiece together with the argon ions. When the number of evaporating material ions plated on the surface of the workpiece exceeds the number of sputtered ions, they gradually accumulate to form a layer that adheres firmly to the workpiece. Coating on the surface of the workpiece.
3. Classification
① Magnetron sputtering ion plating
②Reactive ion plating
③Hollow cathode discharge ion plating
④Multi-arc ion plating.
4.Features
The ion plating technology of the pvd coating machine has good coating adhesion performance. A tensile test on the specimen after ion plating showed that when it was pulled until it was about to break, the coating still plastically extended along with the base metal, and no peeling or peeling occurred; It has strong ability, so this method is very suitable for inner holes, grooves and narrow slits on plated parts, and other parts that are difficult to plate with other methods; the coating quality is good, the ion plating coating has a dense structure, no pinholes, no bubbles, Uniform thickness; simplified cleaning process.
