摘要
Several types of coatings, designed to improve the resistance of aluminum alloys to corrosion in seawater, were examined. A coating with a thickness of approximately 30 mu m was applied to the surface of aluminum alloy 3003, and after creating an artificial defect by means of a knife-edge, a corrosion test was carried out in 3% NaCl solution at a temperature of 70 degrees C and pH 1.5. The test results showed that a fluorine resin and sol-gel coatings both had excellent barrier abilities. The fluorine resin coating had self-healing abilities, and this was improved by the addition of a metal powder.
