What is Passivation

What is Passivation

Passivation is a way to convert metal surfaces into states that are not easily oxidized and to delay the corrosion rate of metals. In addition, an active metal or alloy, in which the chemical activity is greatly reduced, and become a noble metal state phenomenon, also called passivation.

Passivation Advantages

1) Compared with the traditional physical sealing method, the passivation process has the characteristics of absolutely not increasing the parts thickness and changing the color, improving the precision and added value of the product, making the operation more convenient;

2 ) Because the passivation process belongs to the reactive state, the passivation agent can be added and used repeatedly, so the life expectancy is longer and the cost is more economical.

3) Passivation causes the metal surface formation oxygen molecule structure passivation film, the film density, the performance is stable, and has the self repair function in the air simultaneously, therefore compared with the traditional antirust oil method, the passivating film formed by Passivation is more stable and has more corrosion resistance.

Passivation Applications

1. Long string pieces passivation

2. Long strip pieces passivation

3. Flat pieces passivation

4. Surface passivation

5. Small pieces passivation
