Atmospheric corrosion happens when metal meets air full of moisture and salt. This is common on boat exteriors, where metal faces harsh sea conditions.
Immersion Corrosion
Immersion corrosion occurs when metal is in water, especially warm saltwater. This speeds up corrosion, a big worry for boats in the water for long times.
Galvanic Corrosion
Galvanic corrosion happens when different metals are in water or saltwater and touch each other. This can quickly damage the more reactive metal, harming boat parts.
Pitting Corrosion
Pitting corrosion creates small holes and cavities in metals. It’s a big problem where metal is not protected or meets corrosive agents.
Poultice Corrosion
Poultice corrosion occurs when metal is covered by dirt and moisture. This creates a corrosive environment that slowly damages the metal.
Erosion Corrosion
Erosion corrosion happens when moving water wears away metal. It’s seen where water flows fast, like around propellers or thru-hull fittings.
Stress Corrosion
Stress corrosion creates tiny cracks in metal from bending or shaping. These cracks can start more corrosion, weakening boat parts.
| Type of Corrosion | Description |
|---|---|
| Atmospheric Corrosion | Occurs when metal is exposed to air containing moisture and salt |
| Immersion Corrosion | Takes place when metal is submerged in water, especially warm saltwater |
| Galvanic Corrosion | Occurs when dissimilar metals are immersed in a conductive solution and are electrically connected |
| Pitting Corrosion | A localized form of corrosion where tiny holes and cavities are produced in metals |
| Poultice Corrosion | Happens when a metal is covered by absorbent materials, dirt, and debris, trapping moisture against the unprotected metal surface |
| Erosion Corrosion | Occurs when the constant velocity of moving water gradually wears away the metal |
| Stress Corrosion | Can form hairline cracks in metal fittings that have been formed through bending or metal working |
Knowing these corrosion types is the first step to protect your boat. By spotting each type, you can take steps to prevent and fix corrosion. This keeps your boat healthy and performing well for years.
