🔍 Key Concepts

• Galvanic series in seawater and where aluminum, bronze, lead, and stainless steel fall on it • The idea that metals that are more noble (toward the cathodic end) corrode less in a galvanic couple • How passive oxide films (like on some stainless steels) can reduce corrosion in well‑aerated seawater

💭 Think About

• Think about which of the listed metals is generally considered more noble (less active) in the galvanic series when in seawater • Consider which metals are commonly chosen for long‑term underwater hardware on boats and why • Ask yourself which of these metals is more likely to form and maintain a protective surface film in seawater under normal conditions

✅ Before You Answer

• Check a simplified galvanic series in seawater and compare the relative positions of aluminum, bronze, lead, and stainless steel • Verify which material is typically used for propeller shafts and underwater fittings because of its resistance to seawater corrosion • Make sure you distinguish between general corrosion resistance and problems like pitting or crevice corrosion that may only occur in certain conditions
