Students will learn how to properly conduct a corrosion survey aboard vessels of varying hull types. They will learn enough basic electrical and corrosion fundamentals to understand how a boat’s electrical system affects corrosion aboard. Students will learn about environmental factors that promote corrosion and affect the rate of corrosion. Students will learn about cathodic protection and how it’s appropriately applied. Students will practice taking corrosion potentials aboard a variety of vessels.
Students learn how to:
- Describe the basics of corrosion processes .
- Describe and use the galvanic series chart.
- Take proper electric potential readings aboard a vessel.
- Differentiate material properties of different alloys and their specific corrosion issues.
- Recognize the effects of the AC Shore power cord on the hull potential.
- Use a variety of specialized equipment used in the corrosion survey.
- Properly test galvanic isolators and understand their function.
- Identify the advantages and disadvantages of polarization and isolation transformers.
- Take corrosion preventative measures for hull materials such as wood, aluminum, steel and fiberglass.
- Describe galvanic corrosion processes.
- Describe stray current processes.
- Recognize and prevent a variety of corrosion types.
- Select and use specialized equipment for prevention of corrosion.
- Describe the appropriate application of specific sacrificial anode types.
- Complete a corrosion survey and advise the boat owner on appropriate preventive measures.
- Benefit of coating systems to prevent corrosion and reduce the amount of cathodic protection required
