Iranian Company Develops 2 Nanostructured Anodized Coating for Aluminum

Alborz Pasargad Aluminum Company has taken an important step to improve the durability and performance of aluminum profiles by producing two nanostructured technologies in the field of aluminum coating.

These two technologies, which have been awarded nanoscale certification, include nanostructured anodized coating with the ability to be printed with nanoscale structures and corrosion.

The wear and corrosion-resistant nanostructured anodized coating is the result of a controlled anodizing process with a porous structure at the nanoscale. In this process, a special electrolyte solution, proprietary additives, and precise application of electrochemical parameters are used to form a ceramic nanostructure layer based on aluminum oxide (Al₂O₃) on the surface of the aluminum profile or sheet. The structure of this layer consists of nanotubes perpendicular to the surface, which are bonded to the base aluminum as a composite and integrated layer, significantly increasing the surface resistance to corrosion, abrasion and environmental factors.

This technology is specially important in challenging applications such as exterior structures, signboards, railings, doors and windows, and equipment exposed to moisture and industrial pollution. Due to its low coefficient of friction, high color fastness and good appearance durability, the use of this nano-coating not only increases the product's lifespan, but also reduces the need for periodic repairs and replacements.

The second technology, nanostructured anodized coating with infiltration printing capability, has provided a new possibility in decorating and personalizing aluminum surfaces.

This technology, by utilizing the nanoscale porosity created in the surface, allows the penetration of paint or ink into the underlying layer of the coating. As a result, the design and color are fixed within the coating structure and do not fade, scratch or peel, unlike traditional surface printing methods. This advantage is a significant innovation for signage, decorative pieces, and architectural equipment where appearance is of great importance.

Also, in 2023, An Iranian company had produced special aluminum profiles with high resistance to wear and corrosion by using nanotechnology.

The company is the producer of the aluminum profile whose surface is anodized for varying their physicochemical characteristics. It bears desired wear and corrosion resistance.

The generation of a nanoporous structure at the surface of the aluminum profile has led to improving the adhesion of paint on the profile surface, enhancing the wear and corrosion resistances, increasing the paintability, reducing the friction coefficient of the profile surface, and boosting the aesthetic appearance.

The product can be used in building structure like retaining walls and columns, bridges, building doors and windows, fences of staircases and automotive and aircraft industries.
