Write various methods to prevent corrosion.

Explanation

### Step-by-Step Solution:

1. **Understanding Corrosion**:
- Corrosion is the degradation of metals due to electrochemical processes. It typically occurs when metals react with moisture, oxygen, or other environmental factors, leading to rust or other forms of deterioration.

2. **Method 1: Galvanization**:
- This method involves coating the metal surface with a non-corrosive metal, usually zinc. Zinc acts as a protective layer, preventing the underlying metal from coming into contact with moisture and air, which are necessary for corrosion to occur.
