Anticorrosive Effect of Tribulus terrestris on Aluminium in Basic Media

Аннотация

Different plant parts—extracts of Tribulus terrestris were employed against aluminium corrosion in basic media. The corrosion inhibition behavior of alcoholic extract of plant parts was measured by the weight loss method, the thermometric method, the potentiostatic polarization method, and electron impedance spectroscopy. The surface analysis was carried out by Fourier-transform infrared spectroscopy and scanning electron microscopy. The experiments showed an inhibition efficiency >70% with leaves extract in 0.5 M NaOH solution.
