The vast majority of metal corrosion data in the United States are expressed in terms of surface regression rate mpy (mils, or thousands of an inch, per year). Multiply mpy by 0.0254 to obtain millimeters per year (mm/yr). To convert to mass-loss rate, multiply the surface regression rate by surface area and material density, using consistent units. Polymer attack typically involves volume changes, usually increases, caused by liquid absorption; reductions in mechanical properties such as yield strength, tensile strength, flexure strength, and tensile modulus; discoloration; and/or changes in surface texture. Certain plastics are degraded by ultraviolet light, which limits their usefulness in sunlight unless they are pigmented with an opaque substance such as lamp-black carbon.

The attack on metals involves oxidation of neutral metal atoms to form positively charged ions which either enter into solution or become part of an oxide layer. This process generates electrons, which must be consumed by other atoms, reducing them, or making them more negatively charged. Conservation of electrons requires that the rate of metal oxidation (corrosion) equal the rate of reduction (absorption of electrons by other atoms). 35.3.1 General Attack In general attack, oxidation and reduction occur on the same metal surface, with a fairly uniform distribution. Most of the corrosion data in this chapter are for selected materials subject to uniform attack in a given environment. Once a suitable material is selected, further control of uniform attack can be achieved by coatings, sacrificial anodes (see Galvanic Corrosion), anodic protection (see Passivation), and inhibitors. Coatings are many times multilayered, involving both metallic and polymer layers. Inhibitors are additions to liquid environments that remove corrosives from solution, coat metal surfaces to decrease surface reaction rates, or otherwise alter the aggressiveness of the environment. Chemically protective metallic coatings for steels are usually zinc (galvanized) or aluminum (aluminized). Aluminized steel is best for elevated temperatures up to 675 C and for severe industrial atmospheres. Both may be deposited by hot dipping, electrochemistry, or arc spraying. Common barrier-type metallic platings are those of chromium and nickel. The Environmental Protection Agency has severely limited or prohibited the use of lead-bearing and cadmium platings and cyanide plating solutions. Polymer coatings (such as paints) shield metal surfaces from electron-receiving elements, such as oxygen, reducing corrosion attack rates. Under mild conditions, even decorative paints can be effective. Under more severe conditions, thicker and tougher films are used which resist the effects of moisture, heat, chlorides, and/or other undesirable chemicals. Acrylics, alkyds, silicones, and silicone-modified alkyds are the most commonly used finishes for industrial equipment, including farm equipment. The silicones have higher heat resistance, making them useful for heaters, engines, boilers, dryers, furnaces, etc.

35.3.2 Galvanic Corrosion and Protection When two dissimilar metals are electrically connected and both are exposed to the same environment, the more active metal will be attacked at a faster rate than if there had been no electrical connection between the two. Similarly, the less active metal will be protected or suffer less attack because the surface areas of both metals can be used to dissipate the electrons generated by oxidation of the more active metal. The net flow of electrons from the more active to the less active metal increases the attack rate of the more active metal and decreases that of the less active metal. An adverse area ratio is characterized by having a larger surface area of less active metal than that of the more active metal. Cracks in a barrier protective coating (i.e., polymers) applied to the more active metal in a galvanic-couple situation can create an extremely adverse area ratio, resulting in rapid localized attack in the cracks. The standard electromotive force (emf) series of metals (Table 35.1) lists
