    摘要： An anticorrosive film which can be formed without causing any substantial environmental pollution, can effectively prevent any corrosion from occurring through pinholes in a corrosive environment, allows the formation of a contact of high reliability maintaining a low contact resistance, and remains stable for a long time on the surface of a substrate having a gold or gold alloy layer without causing any variation in contact resistance, or undergoing any change in outward appearance. The film is formed by bringing the substrate surface into contact with an aqueous solution containing at least one of mercaptobenzothiazole and its derivatives as represented by the following formula at a concentration of 6 to 30 mmol/l.

    摘要： 1,2-dithiolium compounds are prepared by oxidizing 1,2-dithiole3-thiones. In general, aliphatic-substituted dithiolium compounds have been found to be more stable and more water-soluble than aryl-substituted dithiolium compounds. Dithiolium compounds are useful as corrosion inhibitors in aqueous and/or aerated and/or acidic systems. Their usefulness as corrosion inhibitors is enhanced by the high water solubility and stability of the aliphatic-substituted dithiolium compounds.
