Abstract

The oxidation of thin films of tin in SO2-air atmospheres containing 10%, 20%, 30%, 40%, 50%, and 60% SO2 have been investigated at room temperature. Reaction kinetics were studied by the variation in resistance of thin films and growth patterns by metallography. Addition of SO2 causes an increase in the oxidation rate of thin films of tin. Probable reactions at lower and higher percentages of SO2 have been discussed.

Key words

Oxidation and corrosion growth kinetics resistance variation SO2 atmospheres cathodic reaction migration of cations
