In this investigation, a meticulous comparative assessment was conducted to evaluate the anti-corrosive properties of two glassy compounds, P3 and P4, in a 1 M HCl solution. These compounds, composed of Bi2O3-B2O3- (0.5 V2O5 - 0.5 P2O5) via mixing, were subjected to electrochemical analyses employing polarization and impedance spectroscopy techniques. Our findings substantiate that both P3 and P4 phases considerably attenuate the corrosion rate of steel in the evaluated corrosive milieu. It is imperative to underscore, however, that the compounds P3 and P4 with a distinct structural configuration manifests particularly pronounced anti-corrosive efficacy.
