Corrosion of Mild Steel in Volcanic Soils (2)

Corrosion of Galvanized Steel in Soils

The results of measurements of the corrosion of galvanized steel and of bare steel and zinc as reference materials after exposure to different soil conditions for a maximum of 13 years are reported. The magnitude and progress of corrosion of galvanized steel as determined by weight loss and pitting is interpreted in terms of the environmental conditions to which the specimens were exposed. From...

Inhibition of Mild Steel Corrosion in Sulfuric Acid Solution by 2-Hydropyrimidine-2-Thione Derivative

The corrosion inhibition potential and efficacy of 2-hydropyrimidine-2-thione derivative on mildsteel in 0.5 M sulfuric acid solution was investigated using electrochemical polarization and FTIRspectroscopic techniques. In addition, docking studies were carried out as theoretical investigationof adsorption inhibitor on iron surface. The results of polarization studies indicate...

Novel Corrosion Inhibitor for Mild Steel in HCl

Corrosion inhibitory effects of new synthesized compound namely 5,5'- ((1Z,1'Z)-(1,4-phenylenebis(methanylylidene))bis(azanylylidene))bis(1,3,4-thiadiazole-2-thiol) (PBB) on mild steel in 1.0 M HCl was investigated at different temperatures using open circuit potential (OCP), potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS). Results showed that PBB inhibited m...

A Mechanistic Model of H2s Corrosion of Mild Steel

Glass cell experiments were conducted to investigate the mechanism and kinetics of mild steel corrosion in H2S environments which is accompanied by iron sulfide scale formation. By using the weight change method, the rates of corrosion and scale formation were found. It was also concluded that mackinawite is the predominant type of iron sulfide that formed on the steel surface under the test co...
