Calculation of the surface self-diffusion coefficient, DS, induced by the exchange current density, i0. Application to stress corrosion cracking

Abstract Some stress corrosion cracking (SCC) systems show a relation between the exchange current density (i 0 ) and the crack propagation rate (c.p.r.). In the present publication a method for calculating the surface self-diffusion coefficient as a function of l 0 is proposed. Good agreement is found between the calculated c.p.r. values and those reported in the literature.
