General information
- Short Summary
-
A team of inventors from an established Slovak scientific and research institution have developed a new innovative type of metal matrix composite material for biomedical implants comprising ultrafine-grained zinc (Zn) matrix stabilized with a small fraction of nontoxic nanometric zincite (ZnO) dispersoids.
The preferred cooperation type are commercial agreement or investment agreement. - Full Description
-
A novel bioabsorbable metallic material - ultrafine-grained zinc (Zn) based metal matrix composites (MMC) stabilized and strengthened by a small fraction of nanoscale zincite (ZnO) dispersoids. Zn+ZnO MMC were developed and tailored for the biomedical device application of bioresorbable endovascular stents and orthopedic internal fixators. Zn+ZnO MMC are manufactured by powder metallurgy (PM) approach. ZnO dispersoids originate from passivating ZnO films, which exist on fine as-atomized Zn feedstock powder. Unique refined Zn grain structure obtained by deformation induced during powder consolidation yields the attractive mechanical properties – namely high strengths and ductility (and their combination), and improved fatigue and creep resistance. A primary role of ZnO disperoids is stabilization of a refined Zn grain structure during cold and hot working operations applied during Zn powder compaction and post-processing of Zn+ZnO MMC.
A team of inventors from an established Slovak scientific have developed managed to develop a novel Zn+ZnO MMC, which offer exceptional mechanical properties (tensile strength and elongation), fatigue and creep performance, which is superior to contemporary Zn-based alloys designed for biomedical applications. Unlike to conventional Zn-based alloys, owing to effective stabilization by nanometric ZnO dispersoids microstructural stability and hence a stability of the mechanical properties is granted during storage, postprocessing or service even at elevated temperatures. At the same time, Zn+ZnO MMC show biological and corrosion characteristics, which are comparable to contemporary Zn-based alloys.
The institution is looking for a partner to cooperate with via commercial agreement or investment agreement. - Advantages and Innovations
-
• possibility to manufacture implants with thin strut sections and complex shapes,
• the composite material is manufactured using feasible technological approach, which is easily to upscale at reasonable low production costs,
• the composite material Zn+ZnO MMC offers an exceptional stability of the mechanical properties, such as high tensile strength and ductility, desirable corrosion rate and uniform corrosion behavior, non-toxic biological response, and bacteriostatic effect during the anticipated service of biomedical device, the 2DML exfoliation process is performed in a low shear rate mode (replaces speeds in terms of energy consumption and product quality). - Stage of Development
