TiNi合金具有形状记忆效应及超弹性两种特性,可制作构造简单的驱动元件。这种驱动元件的单位体积做功远比PZT等其它材料的驱动元件大,但是制造这种材料必须经过复杂的塑性加工和热处理的组合工艺,是该材料的缺点之一。日本富士菲尔特工业公司和全泽工业大学的研究人员采用镀镍的纯钛丝,制成三维形状元件后进行扩散热处理,得到新开发的元件,并评价了该元件的性能。这种三维形状TiNi合金元件的制造方法是:在
TiNi alloy has the shape memory effect and superelastic two kinds of characteristics, can produce simple structure of the drive components. The drive unit has more work per unit volume than the drive units of other materials such as PZT, but it is one of the disadvantages of this material to manufacture such a combination of complex plastic and thermal processes. Researchers at Fuji Felt Industries in Japan and AllZa University of Technology used nickel-plated pure titanium wire to fabricate three-dimensional shape elements and then subjected to diffusion heat treatment to obtain newly developed elements and evaluate the performance of the element. The three-dimensional shape of the TiNi alloy element is manufactured by:
