A heat treatment effect on the microstructure and corrosion properties of electrodeposited Zn, Zn-Co, Zn-Fe, and Zn-Ni alloy coatings was studied. Surface morphology examinations were carried out using AFM, while XRD determined metal lattice parameters, texture, and phase composition. Low-temperature annealing (at 225 °C to 176 °C) resulted in the formation of intermetallic Fe/Zn compounds and a transformation of amorphous oxide inclusions to crystalline form, along with a decrease in the Zn lattice parameter for Zn-Co and Zn-Fe alloys. However, these structural modifications did not lead to changes in the corrosion behavior of these coatings. In contrast, the Zn-Ni alloy exhibited significant reduction in the diffraction peak width and a considerable increase in corrosion current following annealing. This effect was attributed to the development of a less disordered lattice for this alloy. The findings suggest nuanced relationships between heat treatment, microstructural alterations, and corrosion performance of various electrodeposited zinc alloy coatings.
