Research of Air Oxidation Kinetics of Ag-10Ni Composite
Keywords:Ag-Ni pseudoalloy, oxidation kinetics, heat resistance.
The paper deals with the research of air oxidation kinetics of silver-based
composite. Oxidation kinetics of silver-based composite material, containing
10 weight percent of nickel, was studied. Changes of specific weight gain
experimental curves in air in the 500-900oС temperature range are well described
by the law of complex parabola. On the basis of this equation calculation
formulas are obtained allowing constructing theoretical oxidation curves of the studied objects, which practically coincide with the experimental results.
The temperature dependence of linear and parabolic constants of oxidation
process is defined.
