What is corrosion resistance? Form of corrosion Corrosion Uniform of general corrosion Crevice corrosion Galvanic corrosion Pitting corrosion Environment corrosion Intergranular corrosion Erosion corrosion Stress corrosion

weak corrosion material use material use Strong corrosion Magnesium zinc cadmium use Strong corrosion material Bronze Stainless steel Titanium use Titanium

How to prevent corrosion To block water and oxygen (plating) : paint, oil, enamel 2. Cathodic protection : To plat reactive larger metal 3. Alloy : First property changes different property
