Aluminiumbelægning

Aluminiumbelægning refers to the process of applying a layer of aluminum onto the surface of another material. This can be achieved through various methods, including thermal spraying, electroplating, sputtering, and hot-dip coating. The primary purpose of an aluminiumbelægning is often to enhance the properties of the substrate material, providing protection against corrosion, improving reflectivity, or offering a decorative finish.

In construction and industrial applications, aluminiumbelægning is frequently used to protect steel structures from atmospheric corrosion. The aluminum layer acts as a sacrificial barrier, corroding preferentially to the underlying steel. This significantly extends the lifespan of bridges, pipelines, and other metal components exposed to harsh environmental conditions. Another common use is in the packaging industry, where thin aluminum foils are often applied to paper or plastic to create barriers against moisture, oxygen, and light, preserving the contents.

The appearance of an aluminiumbelægning can vary depending on the application method and the desired finish. It can range from a matte, silvery appearance to a highly polished, reflective surface. The thickness of the coating is also controllable, allowing for tailored performance characteristics. The durability and effectiveness of an aluminiumbelægning are influenced by factors such as the preparation of the substrate surface, the coating process itself, and the environmental conditions to which the coated material is exposed.
