The electrochemical corrosion behaviour of mild steel embedded in concrete, and partially immersed in 0.2M H2SO4, was studied in this investigation at ambient temperature by potential monitoring technique. The experimental work was performed with a digital multimeter and a Cu/CuSO4 electrode (CSE) as the reference electrode. Extracts of carica papaya leaves and sodium nitrite (NaNO2) in differe...

The corrosion resistant coatings used conventionally are susceptible to degradation, leading to pitting corrosion. This report summarizes the corrosion resistant nature of thin films of Cu-TiO2 coated on mild steel, in different corrosion environments. Nano meter thick (100nm, 125nm, 150nm) composite coatings were coated on steel substrate by RF magnetron sputtering technique. The required targ...
