INHIBITION EFFECTS OF Co+2, Ni+2 La+3 AND Ce+3 IONS ON THE CORROSION OF ALUMINIUM AND ALUMINIUM ALLOYS IN THE NaCl SOLUTION

Corrosion inhibitors are widely used in aerated neutral sodium cloride solution. In this study, the effect of metal cations (Co+2, Ni+2, La+3 and Ce+3 ) on the corrosion of aluminium and its alloys in an aerated 1 M NaCl solution were investigated by polarisation measurements. The inhibition efficie...

Description
Summary:Corrosion inhibitors are widely used in aerated neutral sodium cloride solution. In this study, the effect of metal cations (Co+2, Ni+2, La+3 and Ce+3 ) on the corrosion of aluminium and its alloys in an aerated 1 M NaCl solution were investigated by polarisation measurements. The inhibition efficiencies of metal cations were investigated by obtaining current-potential curves in 1M NaCl solution and by calculating corrosion characteristics from current-potential curves. Electrochemical studies showed these cations to axhibit inhibitive effect on the corrosion of aluminium alloys in the studied solution.
