Structural and microstructural analysis of Zn-Mo alloy layers electrodeposited from aqueous citrate solution

Abstract

The paper presents results of the phase-composition and microstructure studies of the Zn-Mo alloy electrodeposited layers. The Zn-Mo coatings are electrodeposited from sulphate-citrate electrolytes on a steel substrate. As revealed in SEM, TEM and x-ray diffraction studies, the coatings consist of the phase crystallized in hexagonal system and contain less than 0.8% wt. Mo built-in the Zn-crystal structure. The presence of Mo atoms causes fragmentation of the crystallites.
