通过研究球磨工艺、超声分散工艺以及超声分散结合滴定工艺三种制备CNTs/HAp复合粉体的工艺，认为以纯超声分散工艺效果最佳。根据DSC曲线确定了两种烧结曲线。经冷压成型、冷等静压成型，600℃真空热处理结合真空或Ar保护无压烧结制备出了CNTs/HAp复合材料。加入CNTs后CNTs/HAp复合材料的弯曲强度与断裂韧性都有提高，但提高的幅度不同。通过TEM、SEM观察了复合材料的粉体及断口情况，确定出了一个合理的CNTs/HAp复合材料的制备工艺。

为提高磷酸钙骨水泥（calciumphosphatebonecement，CPC）的力学性能，扩大其临床应用，制备了碳纳米管（carbonnanotubes，CNTs）增强的CPC复合材料。在复合材料微观结构观察中发现：CNTs在骨水泥固化体中以一种新颖的形式存在，即CNTs在基体中已失去本来形貌，骨水泥水化产物羟基磷灰石（hydroxyapatite，HA）在其表面生长包覆，最终形成了HA/CNTs复合增强体。对该复合增强体的形成过程进行了研究，并提出了HA在CNTs上吸附生长的模型。

By means of different checks and measures, we observed and analysed the microstructure of Fe-Al/Al2 O3 composite material. We found that not only intragranular nanostructure grains and rod-like crystals but also fine-grained structure of the composite material as well as the bridging of the Fe-Al intermetallics compound contribute to the material's strength and toughness. It is shown that the strengthening and toughening of the Fe-Al/Al2 O3 composite is the joint effect of a multiplicate strengthening and toughening mechanism.

本文主要对微孔型HAp基生物材料的制备工艺及成孔机制进行了初步研究。研究发现，经冷压成型、等静压成型后的坯体再用无压烧结可制得孔径不等的微孔型HAp-ZrO2复合材料。在成型压力、烧结温度及保温时间都相同的条件下，添加剂与纳米氧化锆含量越高复合材料的强度越低，但其最低弯曲强度也达到23MPa，大大高于已报道的多孔型材料。添加剂及纳米ZrO2的加入量是材料中孔径大小及孔隙率高低的关键因素，而成型方式、烧结温度及保温时间等因素对其也有影响。

Fe3M/A1203 ceralllic composites are SOllle of the novel ceralllic composites that have good appliction prospects as catting tools and fomfing dies in this paper, the effects of different sintering technologies on the microslrnclm-e of these composites are conlpared and analysed, the optical micrograph of the composite sample nlade by different ratio and hot press sintering technology being observed and studied The results of experiment indicate that Fe3AI/A1203 composites with fine grains, compact strnctm-e and good mechanical properties can be obtained at about 1400℃ Furthermore, in addition to the sintering pressme, the content of Al203 and the additives ofthe composites, also have an-nnlportant influence on their sintering temperature, lnicrostrnctm-e and characteristics When adjusting the factors appropriately,the composites can be sintered at low temperature.
