The effectiveness of benzotriazole in reducing the corrosive behavior of alkaline Rochelle salt, alkaline glycerol, Calgon, and citric acid on exposed tin-bronze surfaces was studied to determine a safe procedure to utilize these stripping agents. Test pieces of modern metal were immersed in the reagents using two different treatment methods. The effect of benzotriazole was observed by metallographic techniques. The method of pretreatment of the samples with benzotriazole before immersion in the stripping reagents gave successful corrosion inhibition only for the samples in Calgon. The method of direct addition of benzotriazole to the reagent was found to be most effective for the Calgon solution, less effective for the alkaline Rochelle salt and alkaline glycerol and not effective for the citric acid solution.
