What are the adverse effects of corrosion?
उत्तर
The adverse effects of corrosion are as follows:
- Damage to commercial aeroplanes that could result in possible in-flight problems
- Damage to oil pipelines that could cause a costly and dangerous rupture that creates significant environmental damage.
- Damage to bridge supports that could cause a bridge failure
- Release of harmful pollutants from iron corrosion that contaminates the air
- Costs of repairing or replacing household equipment that fails
- Lose of efficiency
- Contamination of product
- Damage of metallic equipments
- Inability to use metallic materials
- Lose of valuable materials such as blockage of pipes, mechanical damage of underground water pipes
- Accidents due to mechanical lose of metallic cars, aircrafts etc.
- Causes pollution due to escaping products from corrosion
- Depletion of natural resource
