Aluminum corrodes when exposed to air, but unlike rusting steel, the corrosion of aluminum's surface layer forms a protective film that prevents degradation of the underlying metal. Following the bath, it is exposed to direct electric currents. Corrosion is a diffusion-controlled process, and occurs on exposed surfaces. Some corrosion mechanisms are less predictable and less visible. Is the chemical treatment of a stainless steel surface with a mild oxidant such as a nitric acid or citric acid solution. This is typically done to remove any foreign material from the surface of the metal which enhances the corrosion resistance of the stainless steel surface and accelerates the re-formation of the passive layer. However, that film breaks down in some harsh environments, such as seawater, leaving the metal vulnerable. Usually, the metal is submerged in a chemical bath. Used with orthodontic, orthopedic and surgical equipment as well as by industrial, marine and aircraft manufacturers. Corrosion is the gradual destruction of metals by chemical reactions. This process increases the metal's surface shine, durability and corrosion-resistance. His paper is published in the ACS journal Industrial & Engineering Chemistry.
