Surface treatment process implementation for aluminium sealing to improve anti-corrosion properties
- Advanced Materials
- Advanced Manufacturing
The achieved objectives of the Project include the development of the solution by optimising the anodising and sealing; characterisation of the anodising and sealing performance (composition, thickness, durability); development of new alternatives in KET TCs’ laboratories; and the evaluation of corrosion performance of the anodised and sealed aluminium. Such a systematic approach provided qualitative and quantitative indicators of the preparation and final performance.
The key outcomes of this Project are the efficient optimisation of the current manufacturing process and characterisation of the prepared coating systems. The optimised solution is more user-friendly because the process can now be controlled under less strict conditions. Also, the production can be carried out with a reduced amount of used hazardous chemicals.
Key success factors
The key success factor was the combined multidisciplinary knowledge of the company and the KET TCs.
Such an approach gave a better insight into the anodisation processes, and the KET TCs’ experience in the corrosion protection coating development and characterisation in the laboratories brought about new ideas. Active corrosion protection with cerium salts and hybrid materials are the future of a novel coating system. The final coatings assure efficient active corrosion protection, which is an important improvement compared to the traditional sealing process. Based on the successful cooperation within the Project, there is no doubt that the collaboration between Gabrijel Aluminium and KET TCs will continue in the future.
