Influence of vanadium on the corrosion behavior of high manganese steel in 0.5M H2SO4 solution

A. GHARBI, H. MAOUCHE, O. GHELLOUDJ, C.E. RAMOUL

Abstract : The effect of vanadium on the corrosion behavior of high manganese steel in 0.5MH2SO4 solution has been investigated using potentiodynamic polarization, linear polarization and impedance spectroscopy.The results showed that the addition of vanadium in high manganese steel decreases the corrosion current density from2.1mA.cm-2 to1.29mA.cm-2. The impedance diagrams show the existence of a single capacitive loop that is attributed to the charge transfer reaction and time constant of the electric double layer.

The results have shown that the addition of vanadium to high manganese steel decreases the corrosion current density from 2.1 mA cm¯² to 1.29 mA cm¯².. Impedance diagrams show

Recently, it was shown by STS on the other (inequivalent) twofold surface of d-Al–Ni–Co, that the local electronic density of a certain subset of rows, which we define as subset

This last assumption could explain the low value of the dielectric constant and the behavior observed in thick ceramics layers based on TiCl 3 , where the grain size ranges between

Its dependency on temperature is weak relative to mass flow rate, and consequently, the Peclet number is only a weak function of equivalence ratio in the liquid-fueled

From the conductivity curves, we can conclude that the less hydrophobic polymer A (short MMA segment) could not restrict the swelling of MAA segments during neutralization, hence

At 900°C, the protective behaviour of HR-120 alloy in presence of sodium chloride under syngas atmosphere can then be attributed to the association of two factors: fast evaporation

Our results show that electrochemical and weight loss corrosion rates considerably increase as the total [HAc + NaAc] is increased, likely down to a
