Abstract
Aluminium alloys are used as lightweight materials especially in the aerospace and automotive industries. They have a number of properties such as high corrosion resistance due to the surface oxide coating, low relative weight and better castability. At normal temperatures, metal oxides are more resistant than the metal itself. The oxide layer is much thinner than the metal but protects it from interacting with the air. The kinetics of oxidation processes is the subject of the current work. As the temperature rises, the oxidation process usually proceeds in the presence of water vapour, and its rate depends on various factors, including the initial oxide layer and oxidation kinetics. The values of the oxidation exponent n аrе calculated for aluminium ribbons with different contents of Fe, Mg and Sb. Their influence on the intensity and two-stage tendency of the oxidation process is established.
