泡沫或多孔钛的制备进展

Progress in Preparation Methods of Titanium Foams or Porous Titanium

摘要:

泡沫或多孔钛是近年来快速发展起来的一类新型钛合金材料。它们兼具结构和功能的双重属性，在航空航天，生物医学，潜艇，汽车和环保等领域有着广阔的应用前景。本文综述了泡沫或多孔钛制备方法的最新进展。这些方法可以归纳为两类：第一类是基于粉末冶金，而第二类是基于物理或化学合成。详细介绍了每种方法的制备过程、工艺特点、所制备泡沫或多孔钛的孔结构特征和性能参数。通过比较分析，最后指出了泡沫或多孔钛制备方法的发展趋势。

Abstract:

As a novel kind of titanium alloy materials, titanium foams or porous titanium has been obtained a rapid development in recent years. They are attractive for aerospace, biomedical, submarine, automobile and environmental protection applications because of their double attribute of structural and functional properties. This paper attempts to give a review on the newly-presented preparation methods of titanium foams or porous titanium since 2004. The methods are divided into two categories. A first group is based on powder metallurgy and the another is based on physical or chemical synthesis. The preparation process, technology characteristics, pore structure and properties of obtained titanium foams or porous titanium of each method are introduced in detail and its development tendency was as-pointed out through a comparative analysis.
