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.
Corrosion is degradation of materialsâ properties due to interactions. with their environments, and corrosion of most metals (and many. materials for that matter) is inevitable. While primarily associated. with metallic materials, all material types are susceptible to.
