| description | 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. |
