Corrosion of Zinc when it reacts with oxygen and HCl to form white coloured ZnCl 2. Corrosion of Tin to form black coloured Na 2 [Sn(OH) 2]. Prevention of Corrosion. Preventing corrosion is of utmost importance in order to avoid huge losses. Majority of the structures we use are made out of metals. Corrosion Rate American Galvanizers AssociationCorrosion of carbon steel and even alloy steels in micro-environments can be very complex. For example, the pH, moisture content, and chloride level are just three of the variables determining the corrosion rate of galvanized steel in soil.. Corrosion charts are difficult to develop because of the many variables present in any given micro-environment.
