Now that we are familiar with the structures of single chain macromolecules, we are in a position to look at some of the interactions of macromolecules with other macromolecules and with smaller molecules.
Corrosion on exposed metal. Corrosion is a natural process, which converts a refined metal to a more stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment.
Most often,  corrosion is the electrochemical oxidation of â¦ a metal (such as iron  corroding to form iron oxide, a.k.a. rust).     Corrosion is deterioration of a substance, usually metal.     Corrosion is slow and continous eting away of metal by the  surrounding.
