多道次搅拌摩擦加工制备生物可降解β-TCP/WE43复合材料
Development of Biodegradable β-TCP/WE43 Composites through Multi-pass Friction Stir Processing
摘要
Abstract
Medical degradable β-TCP/WE43 composite was fabricated via multi-pass friction stir processing(MP-FSP).The microstructure of the β-TCP/WE43 composite was characterized by metallography,scanning electron microscopy,and energy dispersive spectrometer,and the mechanical properties,corrosion resistance,and corrosion-wear performance of the composite were tested and analyzed.The results showed that,after three passes of friction stir processing(FSP),β-TCP particles were well dispersed in the magnesium matrix,and the grains in the stirring zone were refined.MP-FSP can effectively improve the distribution of β-TCP particles in the magnesium matrix and refine the grains,thereby simultaneously enhancing the mechanical properties,corrosion resistance,and corrosion-wear resistance of the composite.These research findings can provide significant guidance for the development of biodegradable magnesium-based implants.关键词
