Vacuum Evaporation Coating Means the process: in vacuum room, heat Evaporation material by heater so that the atoms or molecules in the evaporation material gain sufficient energy to enter the gaseous state. Then the evaporation particle stream will fire direct to substrate, deposite, and come into thin film on the surface. It's one of mainly PVD (Physical Vapor Deposition ) methods.
Vacuum Evaporation Coating has a longer history, and has been used very abroad. Of course, evaporation is older coating method. As the condition of particle stream, evaporation coating is not as good as sputtering coating and Ion plate. But evaporation coating method still have many virtue strongpoint advantage, for example, the equipment and technique are simple.
There are many kinds of evaporation materials, and over one hundred kinds in using. And fabrication methods mainly as below,crystal broken, melt-broken, drawbench, wire-cut, broken granule, milling, press, cast, mold-press and so on. Main shape of product such as wire, powder, granule, pellet, slug, ball, taper...

Vacuum Evaporation Principle: vacuum evaporation coating from vaporize to deposite thin film, the process of physics:
1. Turn other energy source into heat energy, heat the evaporation material so that the evaporation materil been vaporized and sublime, become the gaseity particle ( atoms, molecules or radicle) with energy (0.1-0.3eV);
2. Depart from surface of evaporation materials, the higher energy particle will flight directly to the surface of substrate with any impact;
3. Reach to the surface of substrate, the gaseity particle will agglomerate and become thin film;
4. The atoms of thin film will reform, arrange and come into being chemical bond.

Vacuum Evaporation Materials: There are very various of evaporation material at present, more over one hundred. The shape such as wire, powder, granule, pellet, slug, taper....
