CORROSION TESTS ARE an important tool for evaluating the performance of materials used in scientific, industrial, engineering, consumer, and aesthetic applications, where corrosion was estimated to cost the U.S. economy $276 billion in direct costs annually in 1998, or 3.1% of the U.S. Gross Domestic Product. Corrosion tests are widely used to evaluate the durability of materials of construction in reactive environments. They have a profound impact on society by the influence they have on the choice of materials used, for example, in chemical plants, drilling and mining equipment, energy production facilities, communications equipment, buildings, bridges, spacecraft, monuments, computers, food processing equipment, medical implants, automobiles, and manufacturing facilities. Corrosion tests evaluate a range of material degradation processes that affect the final performance of these materials and directly influence the materials chosen for these applications. These processes involve chemical and electrochemical reactions, and include mechanically assisted corrosion processes and synergies between wear and corrosion. Corrosion tests are used to examine the performance of materials, evaluate alternate materials, develop strategies for protection of materials, and determine the corrosivity of specific environments.
