Corrosion off Copper and Brass in Ammonia Containing ...


Abstract Corrosion of electrolytic tough pitch copper and 70–30 brass in 5 percent NH4OH was effectively inhibited by 1000 ppm (NH4)2CrO4. In 25 percent NH4OH, the same (NH4)2CrO4 concentration effectively inhibited corrosion of 70–30 brass, but for comparable protection of copper, 20,000 ppm (NH4)2CrO4 were required.
