Influence of potential and time on the dissolution of Sn-In, Sn-Zn, and In-Zn alloys with a low content of the second component in chloride media

The dissolution of low-melting alloys with low contents of the more negative component is investigated as a function of time and potential. It is shown, by taking potentiostatic measurements, that several time intervals exist where steady-state and non-steady-state diffusion coefficients are realized. The main dissolution parameters are potential-dependent, and two ranges exist where the steady-state diffusion coefficient varies with the potential.
