Process
Chromate Conversion Coating
1. Definition:
Chromate Conversion Coating, also known as chemical film or chem film, is a surface treatment method used to create a thin, protective layer on metal surfaces. It involves the application of a chemical solution containing chromate compounds, which react with the metal to form a conversion coating.
2. Process:
The Chromate Conversion Coating process typically involves the following steps:
- Surface Preparation:
The metal surface is thoroughly cleaned and prepared to remove contaminants, such as oils, greases, and oxides.
- Immersion or Spray Application:
The metal substrate is immersed in or sprayed with a chromate conversion coating solution, ensuring uniform coverage.
- Chemical Reaction:
The chromate compounds in the solution react with the metal surface, forming a thin film layer.
- Rinse and Dry:
After the desired coating thickness is achieved, the part is rinsed to remove excess chemicals and then dried.
3. Types of Chromate Conversion Coating:
There are two primary types of Chromate Conversion Coating:
- Hexavalent Chromate Conversion Coating:
This traditional method utilizes hexavalent chromium compounds, providing excellent corrosion resistance and adhesion. However, due to environmental and health concerns, its usage is being phased out or restricted in many industries.
- Trivalent Chromate Conversion Coating:
As an environmentally friendlier alternative, trivalent chromate conversion coatings employ trivalent chromium compounds. While offering slightly lower corrosion resistance compared to hexavalent coatings, they still provide effective protection and comply with stricter regulations.
4. Benefits:
Chromate Conversion Coating offers several advantages, including:
- Corrosion Protection:
The conversion coating acts as a barrier, protecting the metal substrate from corrosion caused by moisture, chemicals, and environmental factors.
- Enhanced Adhesion:
The coating promotes adhesion of subsequent paint, powder coating, or adhesive applications, improving overall durability.
- Electrical Conductivity:
Chromate conversion coatings can maintain the electrical conductivity of the metal substrate, making them suitable for electrical and electronic applications.
- Surface Preparation:
The process removes surface contaminants and oxides, ensuring proper adhesion and improved bonding characteristics.
