Mechanism of oxygen adsorption on tantalum

Description

The mechanism of oxygen adsorption and dissolution in tantalum is suggested. The equation of oxygen diffusion in vacancies formed by ion etching in the near-surface layer is solved. The theoretically calculated oxygen diffusion curves are compared with the experimental curves in order to determine the diffusion coefficient. The dependence of the oxygen atom accommodation coefficient on the degree of coating with adsorbed atoms is obtained
