Corrosion of Nonferrous Alloys and Specialty Products
Nonferrous metals and alloys are widely used to resist corrosion. This article describes the most widely used nonferrous metals, such as aluminum, copper, nickel, and titanium. It also provides information on several specialty nonferrous products that cannot easily be categorized by elemental base.
This article focuses on the various forms of corrosion occurred in the passive range of aluminum and its alloys, namely, pitting corrosion, galvanic corrosion, deposition corrosion, intergranular corrosion, stress-corrosion cracking, exfoliation corrosion, corrosion fatigue, erosion-corrosion, atmospheric corrosion, filiform corrosion, and corrosion in water and soils. It discusses the effects of composition, microstructure, stress-intensity factor, and nonmetallic building materials on the corrosion behavior of aluminum and its alloys. The article also describes the corrosion resistance of anodized aluminum in contact with foods, pharmaceuticals, and chemicals.
