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)
