Studies on preparing and corrosion inhibition behaviour of quaternized polyethyleneimine for low carbon steel in sulfuric acid

Improvement of corrosion resistance of AA6061 alloy by tapioca starch in seawater

“…to lower current densities) upon the addition of tapioca starch. These results indicate that tapioca starch acts as a mixed-type corrosion inhibitor with predominantly control of anodic reaction [17]. This means that this natural product have significant effects on retarding the anodic dissolution of aluminum alloy and inhibiting the cathodic hydrogen evolution reaction.…”

Improvement of Corrosion Resistance of Aluminium Alloy by Natural Products

“…Flakes showing corrosion products like metal hydroxides and its oxides can be observed, however no pits or cracks were noticed (Gao et al, 2008). The figures also show the presence of micro organisms (plankton) on the surface of the specimen which contributes to the corrosion process.…”

“…The simultaneous adsorption of the four functional groups forces the natural honey molecule to be horizontally oriented on the surface of Al-Mg-Si alloy (Gao et al, 2008). As the corrosion resistant concentration increases, the area of the metal surface covered by the corrosion resistant molecule also increases, leading to an increase in the IE.…”

Study on the effect of vanillin on the corrosion inhibition of aluminum alloy

“…2 and Table 1, it can be observed that the addition of vanillin at all the studied concentrations decreased the anodic and cathodic current densities, and resulted in significant decline in the i corr . This indicates that vanillin shifted to smallest i corr values and showed leftward displacement in both anodic and cathodic branches of the curves, thus, acting as a mixed-type inhibitor [23], and the decrease is more pronounced with the increase in the inhibitor concentration.…”
