write a short note on corrosion
Answers
Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually a metal) by chemical and/or electrochemical reaction with their environment.
Answer:
Corrosion is the breakdown of materials due to chemical reactions. It is usually oxidation with air molecules and often in the presence of water. Corrosion also occurs when an acidic or basic material touches another material. When a material corrodes, its physical properties change. Problems with corrosion are mostly with metal, though other materials can corrode. Corrosion is a form of erosion. Some materials, such as stainless steel, are highly resistant to corrosion.One form of high temperature corrosion can lead to the formation of compacted oxide layer glazes, which under certain circumstances reduces wear.
Iron corrosion is called rusting.
