The effects of copper sulfate concentration in the plating solution on the composition,the structure and the anticorrosion properties of Ni-Cu-P deposited coating were studied by EPMA、XRD and polarization curves.The anticorrosion properties of Ni-Cu-P deposited coating was optimal as the copper sulfate concentration in the plating solution was 0.5 g·L-1.The electrochemical anticorrosion properties of Ni-Cu-P,Ni-P deposited coatings and copper plates were investigated in the gas condensate.The self-corrosion potential of Ni-Cu-P deposited coatings was low,the self-corrosion current density was small,and the electrochemical impedance was the highest.Therefore,the electroless Ni-Cu-P coatings can be used as anticorrosion cover and anodic sacrificial protective coatings of copper …

The inhibition effect of glutamic acid towards the corrosion of X65 steel in hydrochloric acid solution(10%) was investigated using polarization techniques、electrochemical impedance spectroscopy(EIS) and SEM.The corrosion rate,corrosion potential(Ecoor),polarization resistance(Rp) and inhibition efficiency(η) were determined.The results revealed that the inhibitor is a mixed type inhibitor.It has promising corrosion inhibition efficiency at low concentrations.The inhibition efficiency(η) increased with increasing the concentration.The maximum inhibition efficiency appeared at 0.3 g·L-1.
