Abstract
The effect of a concurrent substitution of tin for aluminum on the corrosion rate of the latter in hydrochloric acid solutions is studied. In the case of an insignificant contribution of the contact exchange current (shortly named “metal depolarization”), the aluminum corrosion rate is determined by its surface coverage with tin and the deposition time. Nonmonotonic time dependence of the corrosion rate can be associated with the kinetics of tin deposition. The equation estimating the inhibition coefficient as a function of the aluminum surface fraction occupied by the tin deposit is given.
