Corrosion and Wear Properties of Cr Coating and ZrO2/Cr Bilayer Coating on Zr-4 Alloy

نویسندگان

چکیده

In this study, duplex surface treatments were used to prepare a ZrO2/Cr bilayer coating on zirconium alloy cladding for enhancing the wear and corrosion behaviors. The cross-section morphology of coated Zr-4 was characterized; results show that Cr- ZrO2/Cr-coated samples had similar morphology, more obvious undulates could be observed than pure Cr owing rough plasma electrolytic oxidation coating. Wear electrochemical behavior in 1200 mg/L H3BO3 2.2 LiOH solutions original investigated. test indicated exhibited better resistance alloy. potentiodynamic polarization curves suggest pitting occurred due dual protection PEO layer also investigated under constant load 5 N. reveal resistance, found significantly enhance

Direct Electrosynthesis of Polyaniline–Fe2O3 Nanocomposite Coating on Aluminum Alloy 5052 and Its Corrosion Protection Performance

The synthesis of polyaniline- Fe2O3 nanocomposite coating on aluminum Alloy 5052 (AA5052) surface has been investigated by using the galvanostatic method. The anticorrosion performance of polyaniline-Fe2O3 coating was investigated in 3.5% NaCl solution by the open- circuit potential (OCP), Tafel polarization technique and Electrochemical Impedance Spectroscopy (EIS). The corrosion rate of polya...

Graphene: corrosion-inhibiting coating.

We report the use of atomically thin layers of graphene as a protective coating that inhibits corrosion of underlying metals. Here, we employ electrochemical methods to study the corrosion inhibition of copper and nickel by either growing graphene on these metals, or by mechanically transferring multilayer graphene onto them. Cyclic voltammetry measurements reveal that the graphene coating effe...

Enhancement of Adhesion Properties, Corrosion Resistance and Cathodic Disbonding of Mild Steel-Epoxy Coating Systems By Vanadium Conversion Coating

In this study, vanadium conversion coating(VCC) was deposited on the surface of soft-cast steel (St-37).  A thermoset coating was enforced on the VCC and blank substrates. The surface was characterized by field emission scanning electron microscope (FE-SEM), elemental mapping of energy dispersive X-ray (EDX) and atomic force microscopy (AFM). The adhesion strength...
