Two component design total ankle replacement is based on restricted type design to prevent dislocation ,and make syndesmosis union to enlarge tibia component contact area and stability. Three component design total ankle replacement is based on unrestricted type design. Components are mimic to anatomic shape ,and congruent polyethylene insert was also characterized. Successful total ankle replacement depends on reasonable prosthesis design and rational contact stress .

二件式人工踝关节，其设计理念，在於以高限制型设计，避免脱位之产生，并以胫骨腓骨骨联合扩大胫骨元件的接触面积与稳定度；三件式人工踝关节，主张以非限制型设计，近於解剖形状之元件，以及与关节面一致构形的聚乙烯内衬为其特点成功的全踝人工关节置换术仰赖合理的踝关节设计以及合理的接触压力。

Little overdose aluminum caused that the displacement reaction occurred between Al and TiO2 with releasing much heat, and Al2O3 and free Ti were formed, then the active Ti combined with C and produced TiC; more overdose aluminum caused the thermit reaction happened between Al and TiO2, and was generated, then Al3 Ti combined with C and produced TiC.

首先在无过量铝的情况下，Al与TiO2发生置换反应，生成了Ai2O3和游离态，而后游离态与C结合生成TiC；而存在过量铝的情况下，首先发生铝热反应生成Al3Ti，进而Al3Ti与C结合生成TiC。最终完全获得Ai2O3-TiC/Al复合材料。
