Electrodeposition Based Preparation of Zn–Ni Alloy and Zn–Ni–WC Nano-Composite Coatings for Corrosion-Resistant Applications

Zinc (Zn) is one of the five most widely consumed metals in world. Indeed, more than 50% all zinc produced used zinc-galvanizing processes to protect steel from corrosion. Zn-based coatings have potential for use as a corrosion-resistant barrier, but their wider restricted due poor mechanical properties Zn that are needed and other rusting. The addition alloying elements such Ni (Nickle) WC (Tungsten Carbide) coating can improve its performance. This study investigates, corrosion performance Zn–Ni Zn–Ni–WC composite nanocoatings fabricated on mild substrate an environmentally friendly bath solution. influence nanoparticles deposition was also investigated. surface morphologies, texture coefficients via XRD (X-ray diffraction), SEM (Scanning Electron Microscopy), EDS (Energy-dispersive X-ray spectroscopy) were analyzed. electrochemical test polarization curves (PC) impedance spectroscopy (EIS) resulted rate 0.6948 Å/min nanocoating, 1.192 coating. results showed nanocoating reduced by 41.71% 8.56% increase microhardness compared hardness These augmented better wettable characteristics zinc, which developed good interfacial metallurgical adhesion amongst elements. novel nanocomposite achieved great improvement property protection surface.
