Developed especially for the functional improvement of aluminium materials (hard anodising) HART-COAT® is versatile, and can coat almost any aluminium wrought, cast and die-cast alloys.
Coating takes place in a cooled acid electrolyte, and the workpiece is connected in series as an anode. It is oxidised in the course of the treatment.
Once the oxidation process is complete, the surface of the treated workpiece changes into a ceramic-like layer. This aluminium oxide layer, which is composed mainly of amorphous y-aluminium oxide, takes the shape of regular cells vertical to the workpiece surface, encases the workpiece and protects it against wear and corrosion.
Materials that have been treated with HART-COAT can be used in a range properties, including:
- Mechanical engineering
- Metal fittings sector
- Automotive sector
- Office and data technology
- Energy and reactor technology
- Household appliance industry
- Food processing industry
- Medical technology
- Measuring and control technology
- Pharmaceutical industry
- Defence sector
