Abstract

Corrosion inhibition properties of nanobis[3-(trimethoxysilyl)propyl]amine on corrosion of borosilicate 7740 Pyrex glass in a solution of synthesized HBF4was analyzed through gravimetric, galvanostatic discharge, polarization Tafel, and EIS techniques. The results revealed that the degree of inhibitory effect rose with concentration. Further, kinetic and thermodynamic effects of temperature on corrosion rate were studied. Polarization and adsorption isotherm studies revealed that nanobis[3-(trimethoxysilyl)propyl]amine is a good anodic-type inhibitor. It was found that the adsorption isotherm can be described by the Langmuir model. Furthermore, microscopic surface analyses such as AFM, SEM, and EDX were used to characterize the surface morphology of borosilicate glass specimens.
