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 the process by which metal degrades in the presence of various oxidizing agents in the environment. Corrosion takes many forms and can have many root causes. One common example of this is the process of rusting, during which iron oxides form in the presence of moisture.Corrosion is a serious problem for the makers of buildings, boats, aircraft, cars, and most other metal products.orrosion takes many forms and can have many root causes.
