China Aluminum Network – When people refer to "Ce aluminum," they are usually talking about a new type of composite coating made from pure aluminum with cerium (Ce) added. This Ce aluminum coating primarily consists of two main components: a pure aluminum layer containing cerium and an epoxy vinyl ester coating. The cerium-containing pure aluminum layer is typically created through thermal spraying, using aluminum as the base material and adding a small amount of cerium during the process. The epoxy vinyl ester coating serves as a protective and functional layer that seals and enhances the performance of the Ce-coated surface. Cerium (Ce) is incorporated into the aluminum coating at a concentration of 0.05 to 0.50% by weight. The remaining impurities, such as iron, copper, and silicon, are kept below 0.30% by weight, with the rest being pure aluminum. In some cases, magnesium may also be used as an additive in the coating. The Ce aluminum coating can be applied to steel surfaces using thermal spray techniques, either by wire or powder. The epoxy vinyl ester lacquer is formulated using ethylene oxide ester resin as the base, with the addition of silicon carbide, aluminum powder, or aluminum slurry. This coating acts as a sealing layer, intermediate layer, and top coat for the Ce-based aluminum coating. It can also be replaced or supplemented with other types of paint coatings depending on the application requirements. This Ce aluminum composite coating is known for its excellent corrosion resistance, durability, and adaptability to various industrial environments. It is widely used in applications where high-performance surface protection is essential, such as in chemical processing, marine engineering, and aerospace industries. The combination of the cerium-enhanced aluminum layer and the epoxy vinyl ester coating provides a balanced solution that offers both mechanical strength and long-term protection against environmental degradation.
