The most common coating technologies in the vacuum coating machine industry include resistance evaporation coating, multi arc ion coating, and magnetron sputtering coating, which are also the most commonly used coating technologies in daily life. Each of the three coating technologies has its own advantages, such as resistance evaporation coating technology, which generally deposits films with low melting points and easy vaporization. Multi arc ion coating technology has strict requirements for workpiece materials, while magnetron sputtering coating technology can almost any material, The application is very extensive, so I won't go into detail here. In the vacuum industry, multi arc ion coating machines use multi arc ion technology. So what is the working principle and application introduction of multi arc ion coating machines that Huicheng Vacuum will talk about today?

Multi arc ion vacuum coating machine is an efficient, harmless, and pollution-free ion coating equipment with the advantages of fast deposition speed, high ionization rate, high ion energy, simple equipment operation, low cost, and large production capacity. Ion plating is actually ion sputtering coating, and for conductive targets, a DC bias power supply is used; Non conductive target material, using a pulse bias power supply. Some multi arc ion coating machines may also require a DC arc power supply or a pulse arc power supply. A bias power supply actually forms a bias electric field between the cathode and the anode at the location of the sample, usually by adding negative high voltage to the cathode. The free electrons on the cathode surface accelerate the emission directionally under the effect of electric field, and the emitted electrons bombard the gas molecules to ionize them. The electrons driven out of the gas are accelerated by the electric field, and continue to ionize other gas molecules, continuously forming the Avalanche effect. The gas is broken down to form a constant ionization current. At this point, the ions are also accelerated, bombarding the target material, driving atoms out of the surface and depositing on the surface of the sample.

The application of multi arc ion coating machine. Multi arc ion vacuum coating machine is used for different grades of hardware products, general building hardware and locks, and can be competent with multi arc ion coating equipment. Medium to high-end products such as watch straps, watch cases, eyeglass frames, mobile phone cases, golf equipment, bathroom fixtures, jewelry, etc. generally use arc/medium frequency (+DC) magnetron sputtering composite coating equipment, and choose the size of the model according to the loading capacity. This device can be plated with decorative films such as gold, rose gold, coffee, brown, bronze, blue, etc.
