Most of the items in our daily life will be coated with a variety of film layers, not only for the sake of beautiful appearance, but also to prolong the life of the items, and it has also been sought after and loved by everyone. Now the pvd coating machine has become our daily life. The inseparable part of the film affects people's living habits and plays a very important role. Then, the following is a vacuum editor for everyone to popularize the common pvd coating machine coating technology names and comments.

       1. Laser beam evaporation laserbeamevaporation: The evaporation of the evaporation material by heating the laser beam.
       2. Indirect heating evaporation: In a heating device (such as a boat-shaped evaporator, crucible, filament, heating plate, heating rod, spiral coil, etc.), the evaporation material obtains the necessary heat for evaporation and transfers it by heat conduction or heat radiation. for the evaporation of the evaporation material.
       3. Flash evaporation: a very small amount of evaporation material is intermittently evaporated instantaneously.
       4. Vacuum sputtering: In a vacuum, inert gas ions bombard atoms (molecules) or groups of atoms from the target surface.
       5. Reactive vacuum sputtering reactive vacuum sputtering: vacuum sputtering of film material with ideal chemical composition through reaction with gas.
       6. Biass sputtering: During the sputtering process, a bias is applied to the substrate and the sputtering of the film layer.
       7. Direct current diode sputtering: through the direct current voltage between the two electrodes, the gas is self-sustained to discharge and the target is used as the cathode for sputtering.
       8. Asymmetric AC sputtering: Asymmetric AC voltage between the two electrodes makes the gas self-sustaining discharge and the target is used as an electrode that absorbs a large positive ion current.
       9. High-frequency diode sputtering: high-frequency discharge is obtained through the high-frequency voltage between two electrodes, so that the target obtains a negative potential for sputtering.
       10. Hot cathode direct current sputtering (three-pole sputtering) hot cathode direct current sputtering: non-self-sustained gas discharge is obtained with the help of hot cathode and anode. The ions generated by the gas discharge are accelerated by the voltage applied between the anode and the cathode (target). And the sputtering of the bombardment target.
       11. Hot cathode high frequency sputtering (three-pole sputtering) hotcathode high frequency sputtering: non-self-sustained gas discharge is obtained by means of hot cathode and anode, and ions generated by gas discharge are accelerated under the action of negative potential on the target surface and bombard the target. .
       12. Ion beam sputtering ionbeamsputtering: sputtering the target using the ion beam obtained by a special ion source.
       13. Glow discharge cleaning: Glow discharge cleaning is a cleaning process in which the substrate and the film surface are subjected to gas discharge bombardment using the principle of glow discharge.
       14. Physical vapor deposition; PVD physical vapor deposition: in a vacuum state, the coating material is vaporized by physical methods such as evaporation or sputtering, and deposited on the substrate, a method for preparing a film layer.
 
The above are the coating technologies of pvd coating machines that we often come into contact with. Many customers know of these vacuum coating technologies, but few people know their full names. Today, I list them one by one, hoping to help everyone.
