Kinetics oxidation aluminum conductive of alloy E-AlMgSi (“aldrey”) with calcium in the solid state
The kinetics of oxidation of the aluminum conductive alloy E-AlMgSi (“aldrey”) with calcium was investigated by thermogravimetry. It has been established that calcium additions to the E-AlMgSi alloy (“aldrey”) reduce its resistance to oxidation in the solid state. It is shown that the oxidation of alloys proceeds according to a hyperbolic mechanism and is of the order of 10-4 kg∙m-2∙s-1.
