The obvious question that springs to mind when researching protective coatings is what are they for?  As I will describe, protective coatings have uses in many forms of industry, for example rocket engines, warheads, medical implants and electronics technology.

Given the rate that modern technology has advanced and is advancing, we have placed huge amounts of stress on the materials we use. As a result, we sometimes need materials, where none currently exist.  So in order to help us bridge the ‘gap’ protective coatings serve as a rather ingenious way to use the materials available and retrofit them for their intended purpose. As a result, these protective coatings have been engineered and allow us to use our structures and fabrications, for longer with less degradation and corrosion as well as higher resistance to both thermal and chemical damage.Protective coatings are used in every form of industry; they are used in manufacturing, construction and technology. They main reason we need protective coatings is a) to protect a structure or fabrication from stress, and B) to extend the objects life.
