1. Surface coating and paint
- Epoxy primer + polyurethane topcoat is one of the most common solutions.
- Galvanized coating is very effective, especially on steel parts.
- Powder coating (electrostatic painting) increases outdoor durability.
- Regular paint inspection should be carried out; scratches and cracks should be repaired immediately.
2. Anti-corrosion oils and coatings
- Anti-corrosion oils are used for moving parts.
- Protective wax or film coatings can be applied to machines that are stored for long periods.
- Water-repellent grease is preferred for bolts, bearings, and connections.
3. Material selection
- Stainless steel (especially 304 or 316 grade) offers advantages in critical areas.
- Aluminum alloys are more durable due to their natural oxide layer.
- Different metals should not be allowed to come into direct contact; otherwise, galvanic corrosion may occur.
4. Water and humidity control
- No pockets where water can accumulate should be left on the machine.
- Drain holes must be kept open.
- A protective tent or covered parking area makes a significant difference.
- The surface should be dried after washing.
5. Cathodic protection
- Used especially in large machines operating near the sea.
- Zinc or magnesium anodes corrode instead of the main metal.
6. Regular maintenance
- Salt, mud, and chemical residues should be cleaned.
- Periodic rust checks should be carried out.
- Initial surface rust should be cleaned with a wire brush/sandblasting and recoated.
7. Prevention of electrical leakage
- Leakage currents can accelerate electrochemical corrosion.
- Grounding and insulation should be checked regularly.
High-risk environments
- Seaside (salty air)
- Fertilizer/chemical plants
- Areas with continuous rain
- Roads salted in winter
