Corrosion comprises the reaction between a metal (or alloy) and its surrounding (environment). The corrosion process depends on the properties of both metal (and alloy) and surrounding (environment). Usually, the more important factors affecting corrosion are concentration, acidity (pH), fluid flow (velocity), temperature, and potential (oxidizing power).

Steel and other ferrous alloys are consumed in exceedingly large quantities because they have such a wide range of mechanical properties, may be fabricated with relative ease, and are economical to produce. However, they have some distinct limitations, chiefly (1) a relatively high density, (2) a comparatively low electrical conductivity, and (3) an inherent susceptibility to corrosion in some common environments. Thus, for many applications it is advantageous or even necessary to use other alloys that have more suitable property combinations. Alloy systems are classified either according to the base metal or according to some specific characteristic that a group of alloys shares. Authors are invited to submit original research articles and reviews to this special issue that include all aspects of corrosion process of the following metal and alloy systems: aluminum, copper, magnesium, and titanium alloys; the refractory metals; the superalloys; the noble metals; and miscellaneous alloys, including those that have nickel, lead, tin, zirconium, and zinc as base metals.

• Corrosion process in nonferrous metals and alloys
• What nonferrous metals and alloys are most likely to corrode
