There is a relation between air pollution and corrosion of materials. A number of air pollutants, such as hydrogen sulfide, carbon dioxide, ammonia, nitrogen oxide,…etc, corrode materials, e.g. carbon steel, copper, aluminum,…etc. Corrosion of materials affects the world economy because the materials, for example, carbon steel, copper and aluminium form the backbone of many industries. The estimated $2.2 trillion annual cost of corrosion worldwide (3 to 4 % of GDP of industrialised countries) reflects in part many decision-makers in industry and government not fully understanding the consequences of corrosion and how critical it is to control it. Therefore, controlling corrosion is a crucial need to protect the environment and to decrease the loss of economy. Better corrosion management can be achieved using preventive methods in nontechnical and technical areas. There are different methods for controlling or inhibiting corrosion, for example, inhibitors and coatings. It is important to care about the environment by using environmentally friendly compounds. There are a number of patents presented in this review article about the environmentally friendly inhibitors and coatings.

Keywords: Materials corrosion, preventing corrosion, environmental pollution, environmentally corrosion inhibitors.
