Vacuum coating technology is an important branch of vacuum application technology, which has been widely used in fields such as optics, electronics, energy development, physical and chemical instruments, construction machinery, packaging, civil products, surface science, and scientific research. The main methods used for vacuum coating include evaporation plating, sputtering plating, ion plating, beam deposition plating, and molecular beam epitaxy. In addition, there is chemical vapor deposition method. Due to the fact that the working principle of various electric vacuum devices is based on electric and magnetic fields to control the movement of electrons in space in order to achieve amplification, oscillation, display of images, and other purposes. Therefore, it is absolutely necessary to avoid collisions between electrons and gas molecules, ensure the movement of electrons in space, prevent cathodic oxidation poisoning caused by the emission of hot electrons, and draw the electronic device into different vacuum degrees required by different electric vacuum devices to ensure the normal operation of the electronic device. At present, the electric vacuum devices produced in the electric vacuum industry mainly include various electronic tubes (rectifier tube, emitter tube, receiver tube, klystron, traveling wave tube, magnetron, photoelectric tube, etc.); Various ion tubes (pump arc rectifier tube, ignition tube, counter tube, thyristor, noise tube, radar wire switch, etc.); Various electron beam tubes (oscilloscope tube, camera tube, cathode ray tube, X-ray tube, image converter tube, etc.); Various electro-optical source tubes (lighting lamps, spectral lamps, instrument lamps, etc.) as well as neutron tubes, electron diffractometers, electron microscopes, X-ray microscopes, various particle accelerators, mass spectrometers, nuclear radiation spectrometers, gas lasers, and the use of electron beams in vacuum for degassing, melting, area purification, melting and drilling of refractory metals and media, slotting cutting, evaporation of radioactive isotopes, welding of refractory metals, and many other aspects.
