Kinetics oxidation aluminum conductive of alloy E-AlMgSi (Aldrey) with cadmium in the solid state

When creating new materials designed to work in particularly harsh conditions, the task of giving them corrosion resistance arises, the practical solution of which is associated with the level of knowledge in the field of high-temperature oxidation of metals and alloys. When using conductive aluminum alloys for the manufacture of thin wire, for example, winding wire, etc., certain difficulties may arise due to their insufficient strength and a small number of bends before failure. The solution of many problems of modern technology is associated with the use of materials with high oxidation resistance. Therefore, the study of the interaction of oxygen with metals and alloys has become of great importance due to the recent widespread use in various fields of science and technology of new materials with special physical and chemical properties. In this series, a special place is given to the aluminum conductor alloy E-AlMgSi (Aldrey). In the literature there is no information about the heat resistance of these alloys doped with cadmium. The process of oxidation of alloys was studied in air under isothermal conditions by the thermogravimetric method with continuous fixation of the sample mass, for an hour at temperatures of 723, 773 and 823 K. On the basis of experimental data, kinetic curves of oxidation were constructed, as well as the dependences of the specific mass increase on the amount of cadmium in the E-AlMgSi alloy (Aldrey), time and temperature. Treatment of quadratic curves of oxidation of alloys at these temperatures is established that the oxidation of alloys obeys the hyperbolic function y = kxⁿ, where n varies from 1 to 4. lgk dependence of 1/T for alloy E-AlMgSi (Aldrey) cadmium shows that with increasing temperature and cadmium oxidation rate increases.
