Abstract
1,3,4-thiadiazole bisdisulfides inhibit copper corrosion by active sul fur in lubricating oils. They react with active sulfur to yield inacti ve trisulfides as determined by Raman spectroscopy and Mass spectrosco py (MS). The thiadiazole bisdisulfide also reacts to form a protective film on the surface of a copper strip. Surface analytical techniques applied to the copper surface show that an organic film is formed chem ically, in which the thiadiazole ring remains.
