Galvanizing with rainbow chromate
Protection of steel from corrosion under various operating conditions. Designation: Ts [thickness] hr. Applicable to all types of steel, cast iron, TsAM. Microhardness: 500-1200 MPa. Specific resistance (18°C): 5.75*10 Ohm*m. Operating temperature: up to +300°C.
Advantages of coverage:
- Protects steel from corrosion in both light and severe operating conditions, even in the presence of scratches or chips of the coating (anodic protection);
- Restores protective properties over time in case of minor mechanical damage (the “self-healing” property of the chromate film);
- Ensures easy screwing of threaded parts;
- Average ductility, in some cases withstands bending, flaring, etc.
Disadvantages of coverage:
- Low abrasion resistance of chromate film;
- protective properties decrease at temperatures above +70°C;
- Increased fragility at temperatures above +250° and below -70°C;
- Low chemical resistance to the effects of products released during the aging of organic materials and in salt environments.
Galvanizing services
Galvanic galvanizing is the application of zinc to iron using an electrochemical process.
The treated surface becomes able to resist corrosive processes. Possible types of chromatization:
- colorless chromate
- rainbow chroming
- black chromate
- olive chromate
The thickness of the coating depends on the operating conditions of the products:
- 6 microns - light operating conditions.
- 12–15 µm - average operating conditions.
- 30 microns - severe operating conditions.
The thickness of the protective layer can be increased to 500 micrometers.
Advantages of galvanic galvanizing:
- Improved performance
- Low cost
- Optimal level of metal protection
- Uniform coverage (no drops, smudges)
- The application of zinc coating to a product does not depend on the structural complexity of the product.
- Decorative coatings (smoothness and shine), parts do not need additional processing.
