The process of electrolytic decorating chromium has the aim of creating deposits of polished, matt, pearl classic” and “3Q7” (glossy, no fingerprints) on smooth or previously satined surfaces.
The chrome-plating has a mainly decorative purpose with obtainable thicknesses of the addition of 0.025 to 0.3 microns certified, always according to the requests.
The objects to be coated, are treated in a solution of chromium salts and the metallic chrome coating is obtained by an electrochemical reduction process.
Good corrosion resistance, excellent esthetic properties are, in fact, particularly suitable for decorative functions.
The corrosion resistance of a decorative chrome deposit depends on the thickness deposited and on the adhesion of the deposit itself, but above all on intermediate treatments such as copper and nickel.
The electroplated chromium layer is not uniform in its distribution, in particular there will be areas such as edges or points where there will be a very marked deposit, while in the holes and in the undercut the deposit will be less.
We can coat the following materials after appropriate preparation treatments:
- Aluminum and its alloys after special preparation
- Carbon steels also heat treated
- Stainless steels
- Cast iron after sandblasting
- Copper and its alloys
The maximum dimensions of the parts that we can work are 1600x1100x300
Possibility of de-hydrogenation and / or lubrication with emulsifiable oils.
