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 reaction with their environment. Corrosion engineering is the field dedicated to controlling and stopping corrosion. Various materials have this property intrinsically, depending upon their corrosion resistance rate. Some other methods can also be used to resist corrosion such as painting, hot dip galvanizing and the combination of these methods with coating. Essentially, corrosion is the process in which a material is oxidized by the environment and loses electrons in its result. Therefore, corrosion resistance is the capability to hold that binding energy of metal and withstand the deterioration and chemical breakdown that occurs during surface exposure to such an environment. There are no materials that are resistant to all corrosion in all environments. Materials must be matched to the environment they will experience. Protective coatings are the most widely used corrosion control technique. Essentially, protective coating materials are corrosion resistant and are a means for separating the surfaces that are susceptible to corrosion attack. Whereas cathodic protection interferes with the natural action of electrochemical cells that are responsible for corrosion. Cathodic protection can be effectively used to resist corrosion of surfaces that are immersed in water or exposed to soil. In material selection for corrosion control, corrosion resistance is an important factor to consider. The book entitled Corrosion Resistance covers the state-ofthe-art technologies, development, and research progress of corrosion studies in a wide range of research and application fields. The applications of corrosion resistance materials will also bring great values to reader's work at different fields. In addition to traditional corrosion study, the book also contains chapters dealing with energy, fuel cell, daily life materials, corrosion study in green materials, and in semiconductor industry.
