what is corroision what are disadvantaged and advantages
Answers
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.
Advantages
1. Corrosion of a material has to be renewed, thus giving scope of continuous demand for materials.
2. Corrosion becomes advantageous when a surface produces an oxide film that will keep corrosion from proceeding further; which happens to aluminum metal.
Disadvantages:
1. Weakens material due to prolonged corrosive action.
2. loss, contamination, and deterioration of the appearance of a material.
3. safety, health and environmental risks due to corrosion, especially in manufacturing plants.
4. Corrosion tends to vent in technical malfunctions in machines.
