Abstract

On the basis of quantum-mechanical calculations within the framework of the cluster models and the literature data the rate coefficients of the elementary stages of the complete system of heterogenous catalytic recombination of dissociated air on the surfaces of thermal-protective β-cristobalite and α-Al2O3 ceramic coatings are determined. The processes of impact and associative recombination of adsorbed oxygen and nitrogen atoms are taken into account.
