INHIBITION OF CORROSION OF α-BRASS (Cu-Zn, 67/33) IN HNO3 SOLUTIONS BY SOME ARYLAZO INDOLE DERIVATIVES

INHIBITION OF CORROSION OF α-BRASS (Cu-Zn, 67/33) IN HNO3 SOLUTIONS BY SOME ARYLAZO INDOLE DERIVATIVES

The influence of some arylazo indole derivatives on the corrosion rate of 70/30 á-brass in 2 mol 1-1 HNO3 was investigated using weight loss and galvanostatic polarization techniques. It was found that the investigated compounds behave as inhibitors. The inhibition efficiency increases with increasi...
