Vacuum in coating application in industry

Vacuum coating technology is applied vacuum technology as an important branch, it has been widely used electro-microcopy, electronics, energy development, physical and chemical equipment, construction machinery, packaging, civil products, surface science and scientific research, etc. Vacuum coating the main methods evaporation plating, sputtering, ion plating, beam and sedimentary plating molecular beam extension, etc. In addition to chemical vapor deposition. If the purpose of the vacuum coating from is to change the material surface physics and chemistry performance, this technology is word of vacuum surface treatment technology in the important part. Now the application of several major do a simple introduction.

First of all, a piece of optics in optical glass or quartz surface one layer or plating layers of different material, can be high after the film reflection or no reflection (namely increased through film) or make any expected the proportion reflect or transmit material, also can make for a certain wavelengths of absorption, and to another one wavelength of transmission of colour filter. High reflection film from the big diameter telescope and all kinds of laser to new beginning, always the building large window coated glass, are really need. It is widely used for the film camera and television camera lens.

In electronics more possession in the vacuum coating is very important position. Various sizes of integrated circuits, including CunZhuQi, unit, the logic element, are the conductive film, insulation membrane and protective film. The preparation of the circuit as a mask use chrome is membrane. The tape, disk, semiconductor lasers, Joseph Hudson device, charge-coupled device (CCD) also use all sorts of films.

In that light, the device, the high video head videos and plane of the display device transparent conductive film, camera tube optical film, XianShiGuan of fluorescent screen aluminium inserted also be adopted vacuum coating preparation.

In components, in a vacuum evaporation nickel chrome, chromium or metal, ceramic can make in the plastic resistance evaporation aluminum, a silicon oxide, titanium dioxide, etc can make capacitors, evaporation selenium can get electrostatic copy machine of selenium drum, evaporation with barium titanate can manufacture magnetostrictive sound components etc. Of the Vacuum evaporation also can be used in the manufacture of superconducting membrane and inertial confinement fusion reaction of coating with beads.

In addition to jewelry, watches and clocks, can also shell surface, textiles, metal decorative pattern, as gold plating adornment such as steamed with film, and for the sputtering ion plating on tool, or mould and other manufacturing super hard film. In the nearly two years rise arc ion plating titanium products, such as the preparation of the stainless steel lamella, mirror board, BaoZhu, armrest, high-grade bed brackets, the stair rail and is currently in vogue.
