摘要：

The effects of the addition of poly(4-vinylpyridine) (P4VP) and its derivative poly(4-vinylpyridine poly-3-oxide ethylene) (P4VPPOE) on the corrosion of Cu60-Zn40 in 0.5M HNO3 have been investigated by potentiodynamic and weight loss measurements. Both of the studied polymers decrease the corrosion rate. Their inhibition efficiency (E%) increases with the concentration. The maximum of inhibition was obtained for P4VPPOE (100 per cent at 10(-5)M). E% obtained from cathodic Tafel plots and weight loss methods were in good agreement. The inhibitors were adsorbed on the Cu60-Zn40 surface according to the Frumkin adsorption isotherm model. P4VPPOE acts as a cathodic inhibitor and its efficiency is temperature independent.
