【摘要】：多孔鈦材料因其優(yōu)良的綜合性能被視為最有潛力的生物醫(yī)用材料之一�？紤]到生物材料在使用過程中必然受到力的作用,重點(diǎn)研究了多孔鈦的力學(xué)性能及其孔結(jié)構(gòu)變形行為。采用添加造孔劑的粉末燒結(jié)方法制備孔隙率為36%~66%、平均孔徑為230μm的多孔鈦。采用掃描電鏡觀察孔結(jié)構(gòu)形貌,通過室溫壓縮測(cè)試檢測(cè)力學(xué)性能。多孔鈦的彈性模量和抗壓強(qiáng)度分別為1.86~14.7 GPa和85.16~461.94 MPa,具力學(xué)性能與人骨的力學(xué)性能相近。建立了多孔鈦的相對(duì)屈服強(qiáng)度和相對(duì)密度間關(guān)系,結(jié)果表明相對(duì)密度是影響多孔鈦力學(xué)性能和變形的主要因素。對(duì)于低相對(duì)密度的多孔鈦而言,其變形方式為孔壁的屈服、彎曲和屈曲;而對(duì)于高相對(duì)密度的多孔鈦,其變形方式主要為孔壁的屈服和彎曲。
