It is triggered by environmental factors, such as water, oxygen and electrolytes.
WebAug 1, 1999 · Graphitic corrosion is a form of de-alloying or selective leaching that occurs in cast iron material. This corrosion mechanism is unique to gray cast irons and is caused by the graphitic matrix present. The graphite is cathodic to the iron matrix. WebTherefore, the galvanic corrosion of aluminum in contact with graphite-loaded neoprene rubber, hot-dip galvanized steel and steel was assessed in a cyclic wet/dry exposure test using mixed-salts spray solutions containing appropriate ratios of sulfate and chloride ion.
WebThe corrosion mechanism is divided into the three following steps: Stage I-the penetration of the corrosive environment into the interior of the MMC caused by (a) pitting of the foil, (b) mechanical or processing surface defect, or (c) capillary wicking of the solution down exposed fibers; Stage II-galvanic corrosion of the aluminum at the G/Al … WebCommon Industrial Materials and their compatibility with deionized water Ratings – Chemical Effect A = Excellent B = Good Minor Effect, slight corrosion or discoloration C = Fair Moderate Effect, not recommended for continuous use. Softening, loss of strength, swelling may occur D = Severe Effect, not recommended for ANY use.
