Scale layers

Scale layers are oxide layers that form on the surface of metals, particularly at temperatures above the ambient temperature. They form as a reaction between the metal and the surrounding oxygen and can affect various metals, including steel, iron, aluminum and copper.

These layers can have a variety of effects, depending on their thickness and composition. In some cases, scale layers can have a protective function, protecting the underlying metal from further oxidation and corrosion. On the other hand, they can also cause undesirable properties such as reduced strength and toughness of the metal.

In the manufacturing industry, scale layers can form during various processes, such as welding, flame cutting, forging or rolling of metals. These layers often need to be removed to improve the quality and integrity of the metal. Various cleaning methods such as sandblasting, pickling, grinding or chemical treatments can be used for this purpose.

The removal of scale layers is in many cases an important step to ensure the quality and performance of metal parts, especially in applications where high strength, precision or surface finish is required. By inspecting and treating scale layers, manufacturers can ensure that their products meet the required standards and specifications and are of high quality and reliability.
