ABSTRACT
Abstract The presented work reports on conditions of electrodeposition of ternary Zn–Ni–P alloys on low carbon steel substrates, using a chloride–sulfate electrolyte containing beta(β)-alanine, NaH 2 PO 2 ·H 2 O and H 3 PO 2 . The chemical and phase compositions of the alloy are determined via scanning electron microscopy (SEM), coupled with an Energy-dispersive X-ray (EDAX) device and X-ray diffraction (XRD) analysis. At pH values of the electrolyte 2–3 and current densities of 1–2 A dm −2 , the electrodeposited alloys contain an amorphous phase and they are essentially Ni–Zn–P alloys with different phosphorous content. The increase of pH up to 4 and higher current densities (5 A dm −2 ) lead to the deposition of Zn–Ni–P alloys with traces of phosphorous, i.e. practically Zn–Ni alloys are obtained. These alloys however differ substantially both in the surface morphology and phase composition as to the usual Zn–Ni alloys, electrodeposited from phosphorous-free electrolytes. The paper reports also results from cyclic voltammetry (CVA) studies on the electrodeposition process of the Zn–Ni–P alloys. Discussion on fundamental aspects of electrodeposition of ternary alloys is made.
