Protective Coatings for Aluminum Alloys
Aluminum is an important material due to its lower density, potentially high strength to weight ratio in mechanical strength, and cyclic flexural performance, depending on alloying elements and microstructure. While alloying yields improved mechanical performance, it can also result in sensitivity to corrosion. The chapter reviews the driving forces for corrosion and surface pretreatments, conversions, and surface coatings for prevention of aluminum or aluminum alloy corrosion. The article discusses how the alloy composition influences corrosion sensitivity and whether and how this sensitivity can be remediated. A few industrial examples of corrosion prevention, corrosion problems, and analysis methods are presented.
