Shielding the base metal from the atmosphere Providing a cathodic or sacrificial protection since zinc is more electropositive than iron or steel Even if the surface becomes scratched and the base metal is exposed, the zinc is slowly consumed while the iron or steel remains protected from corrosion. Individual metal articles, such as steel girders or wrought iron gates, can be hot-dip galvanized by a process called batch galvanizing. A thin even coating is formed. Secondly, because of its electrochemical properties, zinc will sacrificially protect any small areas of damage and the coating may even self heal. With the rapid development of science and society, appropriate dynamic decision making has been playing an increasingly important role in many areas of human activity including engineering, management, economy and others.
