Surface Passivation of Stainless Steel

Date of release:2019-06-29 Author: Click:

6. Stainless steel tube 304 electrophoresis

Electrophoresis is an electrophoretic coating applied at both anode and cathode. Under the action of voltage, the charged coating ions move to the cathode and interact with the alkaline substances produced on the cathode surface to form insoluble substances, which are deposited on the surface of the workpiece.


7. Micro-arc oxidation of stainless steel pipes

Micro-arc oxidation, also known as plasma electrolytic oxidation and micro-plasma oxidation, is a combination of electrolyte and corresponding electrical parameters. The ceramic films mainly consist of matrix metal oxides are grown in situ on the surface of Al, Mg, Ti and other metals and their alloys under the action of high temperature and pressure produced by arc discharge.

Stainless steel passivation, copper passivation, aluminum passivation, coating passivation, steel passivation, other metal passivation


9. Electroplating

Electroplating is the process of plating a thin layer of other metals or alloys on some metal surfaces by using electrolysis principle. It is a process of making metal or other materials adhere to a layer of metal film by electrolysis to prevent metal oxidation (such as rust), improve wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and improve aesthetics. Many coins are also electroplated.


10. PVD Vacuum Coating

Vapor deposition technology refers to a new kind of coating technology which deposits vapor phase materials containing deposition elements on the surface of materials by physical or chemical methods to form thin films.


According to the principle of deposition process, vapor deposition technology can be divided into physical vapor deposition (PVD) and chemical vapor deposition (CVD).


Physical vapor deposition (PVD):


Physical vapor deposition (PVD) refers to the technology of vaporizing materials into atoms, molecules or ions by physical methods under vacuum conditions, and depositing a thin film on the surface of materials through gas phase process.


Physical deposition technology includes vacuum evaporation, sputtering and ion plating.


Physical vapor deposition (PVD) has many advantages, such as wide application of matrix materials and film materials, simple process, material saving and pollution-free, strong adhesion, uniform film thickness, compactness and fewer pinholes.


11. Powder Spraying

Powder spraying is to spray powder coatings onto the surface of workpieces by powder spraying equipment (electrostatic spraying machine). Under the action of electrostatic force, powder will evenly adsorb on the surface of workpieces and form powder coatings. Powder coatings are cured levelly at high temperature and become final coatings with different effects. The spraying effect of powder spraying is in the aspects of mechanical strength, adhesion, corrosion resistance and aging resistance. It is superior to the spraying process, and the cost is also under the same effect of spraying.
