Process of metal corrosion
Webb11 apr. 2024 · Corrosion definition states that it is a natural process that causes the transformation of pure metals into undesirable substances when they react with substances such as water or air. This reaction causes damage or disintegration of metal as it interfaces with the environment and gradually spreads to the entire bulk of the metal. WebbCorrosion is the chemical or electrochemical destruction of metals and alloys in the presence of an environment to form undesirable compounds. Corrosion processes are the reactions of metals with environmental organisms. It is the process of a body gradually deteriorating due to the attack of air gases on the metal's surface.
