Pure zinc exhibits low mechanical properties, making it unsuitable for use in guided bone regeneration (GBR) membranes. The present study focused on the preparation of Zn alloy GBR films using powder metallurgy, resulting Zn-0.5Ti-0.5Fe and Zn-0.5Ti-0.5Mg films. tensile strength pure film measured 85.9 MPa, while an elongation at break was 13.5%. In contrast, demonstrated significantly higher strengths 145.3 164.4 respectively, whereas elongations were 30.2% 19.3%. addition Ti, Fe, Mg substantially enhanced properties alloys. Corrosion analysis revealed that membranes exhibited corrosion potentials -1.298 -1.316 V, with corresponding current densities 12.11 13.32 μA/cm

The hyperpressure solution (HS) is used on Zn‐16Ag alloy to break the limit of atmospheric solid solution, and then precipitation heat treatment performed for 8 h at 100 °C. X‐ray diffraction pattern HS exhibits no obvious second phase peaks, dispersive AgZn 3 phases precipitate after treatment. tensile strength AS‐2 (atmospheric pressure solution–precipitation treatment–rolling) HS‐2 (HS 296 256 MPa, with elongation 38% 59%, respectively. After natural aging, samples decreases by 25.6%, whereas that only 2%. fine diffusion precipitated inhibits growth dynamic recrystallization grains, showing excellent resistance self‐aging. Moreover, a more uniform corrosion mode than immersion tests.

Abstract Controlling degradation rate is essential for the biomedical application of biodegradable Zn alloys. Alloying with soluble elements an effective way to regulate formation second phases, which differ in potential from matrix. The difference exhibits positive or negative effects on corrosion resistance. This study successfully forms MnZn 13 phase nano size by altering ECAP temperature. Subsequently, promotes grain refinement, improvement elongation, and Higher elongation Zn-Mn alloy attributed boundary sliding, deformation twins phase. Meanwhile, incomplete. Corrosion mode alloys without dominated corrosion, accompanied pitting corrosion. increased resistance stems its higher than show a comparable cytocompatibility osteogenic properties. Our findings provide regulating mechanical properties via controlling precipitation.

In the field of degradable metals, Zn-based implants have gradually gained more attention. However, relatively slow degradation rate compared with healing damaged bone tissue, along excessive Zn2+ release during process, limit application implants. The use intermetallic compounds negative electrode potentials as sacrificial anodes is likely to be a feasible approach resolve this contradiction. work, three compounds, MgZn2, CaZn13, and Ca2Mg6Zn3, were prepared. phase structures, microstructures, relevant properties, such thermal stability, in vitro cytotoxicity investigated. XRD patterns indicate that MgZn2 CaZn13 specimens contain single-phase respectively, while Ca2Mg6Zn3 specimen contains Mg2Ca phases. After purifying treatment 0.9% NaCl solution, high purity was obtained. Thermal stability tests suggest possess good below 773 K. melted at around 739.1 Polarization curve show corrosion simulated body fluid (SBF) −1.063 VSCE, −1.289 −1.432 which all than pure Zn (−1.003 VSCE). Clearly, these can act immersion degraded according atomic ratio elements each compound. Besides that, efficiently induce Ca-P deposition SBF. Cytotoxicity demonstrate 10% extracts prepared from exhibit cell activity on MC3T3-E1 cells.
