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.
These can result from a number of causes including the method of application, the condition of the surface or any pre-treatment. Corrosion is an electro-chemical process which transforms steel influenced by oxygen and water, in iron hydroxyde (rust).Corrosion is most often caused when steel is exposed to atmospheric conditions, such as salt, moisture, and oxygen. A protective coating to the steel required to prevent corrosion.Corrosion of stainless steels can be categorised as one of:orrosion is most often caused when steel is exposed to atmospheric conditions, such as salt, moisture, and oxygen.
