Advantages and disadvantages of corrosion |
| Answer» Corrosion is a degradation process applicable mostly for metals. Just like we call rust for Iron. Unlike plastics, corrosion helps disposed metals to get back into the bio-cycle.Advantages:i. Protection : Surface corrosion forms an oxide layer which further protects the inner metal form corrosion.ii. Corrosion prevents corrosion: Some metals like zinc are used as sacrificial anodes to prevent corrosion to other metal.iii. Galvanic corrosion: The principle on which primary batteries work. In which one metal corrodes preferentially to another when both metals are in electrical contact, in the presence of an electrolyte.Disadvantages Of Corrosion: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. | |
