“…The antimicrobial properties of the alloys were evaluated by measuring the diameter of the inhibition zone around the alloys on the agar plates. According to EN ISO 20645:2004 standards, [ 32 ] when the diameter of the inhibition zone is greater than 1 mm, the antimicrobial effect is better, and when the diameter of the inhibition zone is 0 mm, there is no antimicrobial effect. Figure shows the inhibition zone of Zn–1Mg– x Cu alloys after being cultured for 48 h at 37 °C.…”

“…At the same time, grain refinement made the deformation of the alloy more dispersed, enabling it to bear larger deformation and prevent stress concentration; 2) dispersion strengthening—Tong found that the eutectic phase dispersed around the α‐Zn phase inhibits grain boundary movement, [ 34 ] improves grain boundary stability, and thus enhances the strength and hardness of the alloy. Zhan also found that CuZn 5 phase is uniformly dispersed within Zn matrix, [ 32 ] and the strength of the alloy increased from 115.23 to 209.3 MPa. The CuZn 5 phase, which was small and uniformly distributed in the matrix, blocked dislocation movement according to the Orowan mechanism, [ 35 ] and this produced a significant strengthening effect.…”

This work mainly focuses on the mechanical and anti‐infection deficiencies of zinc alloy‐based bone implant materials. Microstructural analysis, tensile testing, electrochemical investigation, immersion experiments and antibacterial testing were used to investigate the effects of Cu content on the mechanical properties, corrosion resistance, and antibacterial properties of the Zn‐1Mg‐xCu (x =0, 0.5, 1, 1.5 and 2wt.%) alloys. The results showed that the addition of Cu to Zn‐1Mg alloy produced a high‐strength and high‐hardness intermediate phase of CuZn5, which significantly increased the tensile strength from 115.2 MPa to 210.6 MPa, elongation from 1.9% to 5.72%, the diameter of the inhibition zone increased from 3.3 mm to 5.1 mm, and the cytotoxicity level of all alloys improved, reaching up to grade 1. Consequently, these findings suggest that the Zn‐1Mg‐2Cu alloy possesses the best mechanical properties, most uniform degradation rate, impressive antibacterial properties, and an excellent biocompatibility. Therefore, the Zn‐1Mg‐2Cu alloy is considered a most preferred material candidate in the field of biodegradable Zn alloys.This article is protected by copyright. All rights reserved.
