Abstract

Polyoxometalates corrosion inhibitors used in experiments were prepared based on literatures, the synthesized products were characterized by infrared spectra and ultraviolet spectra. The test results showed that the synthesized polyoxometalates are of Keggin type. The corrosion inhibition performance was determined using A3 carbon steel specimen by static weight-loss technique in this paper. The corrosion inhibition performance of Na3 [PMo12O40], Na3[PW12O40], Na4[PW11VO40] and Na5[PMo10V2O40] was compared under certain conditions of temperature, corrosion inhibitor concentrations and pH values, and the effects of polyoxometalate concentration and temperature on the corrosion inhibition performance were studied. The experimental results show that all of the synthesized polyoxometalates have a good corrosion resistance, and that the corrosion inhibition efficiency of Na4 [PW11VO40] is the best of all, and it increase with the inhibitors concentration and with the temperature.
