Corrosion Protection of Steel Using Nonanomalous Ni-Zn-P Coatings
A novel technique for obtaining nonanomalous Ni-Zn-P coatings with high Ni content ~74 wt % as compared to 15-20 wt % in the conventional plating method! has been developed. These coatings show promise as a replacement for Cd in sacrificially protecting steel. Ni-Zn-P coatings were deposited using an electroless method from a solution containing NiSO4 , complexing agent and ammonium chloride. V...
متن کاملSynthesis of Polypyrrole/CeO2 Nanocomposite and its Application for Improving the Corrosion Protection of Acrylic Waterborne Coating on Mild Steel
In this work, polypyrrole/CeO2 nanocomposite (NC) was synthesized in the presence of methylorange as a reactive self-degraded soft template. The field emission scanning electron microscopy(FESEM) images indicate that the CeO2 NPs have a nucleus effect and cause a homogenous PPycore–shell type morphology with an encapsulation of the CeO2 core by the PPy shell. The effect ofNC on acrylic waterbor...
متن کاملStudy of the Corrosion Resistance of Ni/CeO2 Composite Coatings Electrodeposited on Carbon Steel in Hydrochloric Acid
The phase formation of Ni-Ce composites onto a carbon steel electrode was investigated using electrochemical deposition. The anticorrosive properties of composite coating in 0.1 mol L HCl solution were studied by Tafel polarization and electrochemical impedance spectroscopy (EIS). Incorporation of CeO2 particles into the Ni matrices was found to improve corrosion resistance of pure Ni coatings....

متن کاملInfluence of electroplating parameters on microstructure and amount of ceramic particle deposition in Ni-Co-CeO2-ZrO2 composite coating
Austenitic stainless steels are high performance steels that have various applications in solid oxide fuel cells and boiler tubes under high temperature operating conditions. The Cr2O3 oxide layer formed on the steel surface becomes unstable at high temperatures and reduces the oxidation resistance of the steel. Therefore, protection of these steels at high temperatures is essential. Therefore,...
