| Abstract Scope |
Zinc alloy has drawn tremendous interest from researchers in the applications of biodegradable implants and sutures. Recently, Zinc alloy with a low percentage of lithium has been studied as a promising candidate due to its high strengthening effect. However, the creep behavior under body temperature of Zn-Li has become troublesome, especially when such alloy is made into suture wires under severe plastic deformation. The refinement of Zn-Li grains strengthens the alloy, but also undermines the creep performance severely. In this work, the incorporation of ceramic nanoparticles shows great promise to not only strengthen the Zn alloy matrix but also promote the thermal stability of Zn alloy. More specifically, Zn-Li-WC nanocomposite is fabricated and characterized to offer superior mechanical properties, better creep behavior, suitable corrosion properties, and adequate in-vitro biocompatibility. |
