A STUDY OF VARIOUS INHIBITORS FOR PREVENTION OF GALVANIC CORROSION.
Abstract
Various types of corrosion inhibitors and metallic salts were evaluated to determine their ability to prevent or retard galvanic corrosion of magnesium-steel assemblies. Screening tests showed sodium mercaptobenzothiazole (NaMBT) to be the most effective for prevention of galvanic corrosion on specimens immersed in a 3 percent salt solution. An attempt was then made to utilize NaMBT in a pretreatment for magnesium-steel couples. A procedure was developed for anodically depositing a coating from a NaMBT bath, however, the coating produced failed to provide the desired corrosion resistance. (Author)
