Abstract
The kinetics of Ag-Ti alloy oxidation has been studied and the acceler ative influence of silver established. A formal approach for its descr iption is proposed assuming a role of Ag as original atomizer of the o xygen molecules. The predicted kinetic law is confirmed by the experim ental results obtained for oxidation of Ag-Ti alloys (0-80 at.% Ag) at 900-1100 K. The values of the rate constant, activation energy and pr e-exponential factor as well as their dependences on the alloy composi tion are also derived.
