摘要
二硼化钛因密度低、熔点高、硬度高、高耐磨性,强耐化学腐蚀和强抗熔融金属侵蚀,被广泛的应用到制备相应的复合材料。二硼化钛复合材料,主要根据其组合相不同分为:二硼化钛-陶瓷复合材料,例如TiC-TiB_(2)复合材料等;二硼化钛-金属相复合材料,例如TiB_(2)/Ni复合材料。本文详细论述了二硼化钛复合材料的不同制备工艺的研究进展,其中包括反应烧结、自蔓延高温合成技术、放电等离子加热烧结、热压烧结、激光熔覆技术等。重点介绍激光熔覆和放电等离子加热烧结制备工艺的原理与方法。
TiB_(2) is widely used to prepare corresponding composites due to its outstanding properties,such as high melting point,low density,extreme hardness,good wear resistance and excellent chemical stability.TiB_(2) composite materials are mainly divided into:titanium diboride-ceramic composite materials,such as TiC-TiB_(2) composite materials,etc;Titanium diboride-metal phase composites,such as TiB_(2)/Ni composites.A number of methods have been reported for the preparation TiB_(2) composites such as reaction sintering,self-propagating high temperature synthesis(SHS),spark plasma sintering(SPS),hot pressing sintering,laser cladding etc.The principle and method of laser cladding and spark plasma sintering are mainly introduced.
