Passivation advantages
1) Compared with the traditional physical sealing method, the  passivation treatment does not increase the thickness of the workpiece  and change the color absolutely, which improves the precision and added  value of the product and makes the operation more convenient.
2) Since the passivation process is carried out in a non-reactive  state, the passivating agent can be added repeatedly to use it, so the  service life is longer and the cost is more economical.CNC Casting Machining Parts Supplier

3)  passivation Promote the formation of the metal surface of the oxygen  molecular structure of the passive film, the film is dense, stable  performance, and in the air at the same time with its own repair, so  compared with the traditional method of anti-rust oil, passivation  formed Passivation film is more stable, more corrosion resistance.
Most of the charge effects in the oxide layer are directly or indirectly related to the thermal oxidation process. In  the temperature range 800-1250 C, the thermal oxidation process with  dry oxygen, wet oxygen or water vapor has three successive stages, first  the oxygen in the ambient atmosphere enters the oxide layer that has  been formed, and then the oxygen passes through the two Silicon oxide diffuses inwardly and reacts with silicon as it reaches the Si02-Si interface to form a new silica. This  continuous oxygen entry - diffusion - reaction process, the silicon  near the interface is constantly converted to silica, the oxide layer to  a certain rate of growth to the silicon chip.
