Sprayed Metal Coatings for Corrosion Prevention

Abstract

Since the time metals were first known, the phenomenon of metallic corrosion has always engaged the attention of mankind. With the almost explosive increase that has taken place in the manufacture and use of metals in the last few decades, this problem has naturally assumed much greater importance and there are now a variety of highly developed processes in use which help in reducing the rate of corrosion and in increasing the useful life of metallic articles. Iron and steel, the most commonly used metals, are usually protected by the application of coatings on their surface, which can be metallic or non-metallic in nature and which have better resistance to the corrosive media than the iron or steel itself.
