WebbCo 3 O 4 layers on an Ni support were prepared by the sol-gel method. Their properties were characterized by TGA, XRD and SEM. For comparison, Co 3 O 4 was also prepared by thermal decomposition of Co nitrate. The surface electrochemical response was studied in alkaline solution by cyclic voltammetry at several potential scan rates. WebbAbstract. Three types of corrosion inhibitors consisting of sodium diphosphate (Na 2 H 2 P 2 O 7), sodium benzoate (NaC 7 H 5 O 2), and sodium tetraborate (Na 2 B 4 O 7) were evaluated to analyze their effectiveness to inhibit the aluminum alloy 3303 (UNS A93303) against corrosion, in water-ethylene glycol (C 2 H 6 O 2) mixture.Potentiodynamic …
