Corrosion of Silver in Sodium Sulfate Solution

An Impedance Investigation of the Mechanism of Pure Magnesium Corrosion in Sodium Sulfate Solutions

Chemical Interaction of Ferric Oxide with Sodium Sulfate at High Temperature Relevant to Hot corrosion

The studies include the results and discussion related with reaction of Fe2O3 with Na2SO4 in presence of SO2 (g) at 800 and 900 C. The iron oxides are produced by the oxidation of iron base alloys in many industrial operations. The metal oxide undergoes certain high temperature chemical reactions in presence of a gas (such as SO2) and molten salts (say Na2SO4). The thermo-gravimetric studies h...

Electrochemical Corrosion of Oxidized Gamma Titanium Aluminide in Ringer's Solution

    Y-TiAl intermetallic alloy have a good potential for use as biomaterial, due to its good corrosion resistance. In this paper, two fundamental electrochemical techniques namely electrochemical impedance spectroscopy and potentiodynamic anodic polarization were used to evaluate the corrosion performance of g-TiAl in Ringer's solution. Surface modification treatments were employed with the pur...

Investigation of Furfural as Corrosion Inhibitor in Hydrochloric Acid Solution

Effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. Lungmuir, Frumkin and Flory-Huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. Furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...
