Abstract

Abstract

Fe-4.8Zn alloy prepared by pulse electrodeposition was heat-treated at 450 ℃ for different holding times. The effects of heat treatment duration on the microstructure, phase composition, elemental distribution, microhardness, and electrochemical degradation behavior of the alloy were systematically studied. The results showed that heat treatment improved the recovery, rearrangement and homogenization of the microstructure on the surface and cross-section of the alloy. XRD analysis indicated that all samples were mainly composed of the α-Fe solid solution, and the diffraction peaks shifted slightly toward higher angles after heat treatment. The distributions of Fe and Zn were uniform, and no obvious elemental redistribution was observed. With increasing holding time, the microhardness of the alloy gradually increased, the corrosion potential shifted positively, the corrosion current density and corrosion rate decreased continuously, and the charge transfer resistance increased progressively. These results indicate that heat treatment duration has a significant effect on the microstructure, mechanical properties, and electrochemical degradation behavior of Fe-4.8Zn alloy, which provides an experimental support for the heat-treatment optimization of Fe-Zn alloys for biodegradable vascular stent applications.
