摘要
分别在1000、1100、1200、1300和1400℃下真空烧结制备了多孔钛试样,并对多孔钛试样进行孔结构、组织结构和性能检测,研究了烧结温度与多孔钛的结构和性能的关系。结果表明:随着烧结温度的提高,多孔钛中颗粒边缘由尖锐变圆滑,孔型由不规则形向圆形转变,烧结颈由细变粗进而出现颗粒表面熔化,孔隙率下降。硬度随烧结温度的提高,呈现先升后降的变化规律,抗压强度逐步提高。
Porous titanium samples were fabricated by sintering at 1000,1100,1200,1300 and 1400℃ in vacuum. The pores, microstructure and mechanical properties of the samples were examined, and the relationship of structure and mechanical properties for the porous titanium sintered at different temperature were studied. The results show that the sintering process starts at 1000℃ and with increasing sintering temperature sharpedge of the particles is gradually melted, the irregular pores become round shape and the porosity decreases. Compressive strength of the porous titanium increases, and its average microhardnesses increases first and then decreases with increasing sintering temperature.
