AN INVESTIGATION ON CORROSION INHIBITORS FOR STEEL IN ETHANOL FUEL BLEND

Nguyễn Đăng Nam

Abstract


Cerium (III) chloride, sodium 4-hydroxycinnamate, and cerium 4-hydroxycinnamate have been successfully characterized as effective anodic, cathodic, and mixed inhibitors for steel in ethanol fuel blend by electrochemical and surface analyses. Electrochemical and surface analyses indicate that good inhibition performances are due to the formation of protective layer as a result of adsorption between the metal and inhibitor components. In addition, the inhibition mechanism of each inhibitor is also suggested and discussed in detail.

Keywords
