In the present work, the capability of SPS process for the production of a complex composite possessing different forms of materials based on WC-Ni-Ti-CNT FGM/laminated composite is investigated. With regard to the unique properties of SPS in producing and densifying a large number of materials, a complex material was prepared as a sandwich structure based on the reaction among Ti, CNT, Ni and WC in various forms consisting of powders, sheets and nano-tubes. The starting materials were initially placed in the graphite mold in the order of Ni powders, WC-10Ni, CNTs coated Ti sheet, WC-15Ni and Ti sheet from bottom to top. The microstructure study showed that the layer of Ni powders was adequately densified as an integrated layer, the second layer, WC-Ni, was attached to the Ni layer from the bottom and, at the top, it was connected to the highly concentrated WC layer formed as a consequence of Ni consumed by Ti to form NiTi and Ni₃Ti compounds. Moreover, the Ti sheets were changed into TiC particles as a result of reaction with WC and CNTs, and the WC-15Ni was placed at the top of this layer by bonding the structure properly; and eventually, the Ti sheet remained at the top of the specimen. The micro-hardness examination of the sample revealed the highest hardness related to the position of Ti-based layer due to the formation of intermetallic compounds and carbides.

在目前的工作中，研究了基于WC-Ni-Ti-CNT FGM /层状复合材料的SPS工艺生产具有不同材料形式的复合材料的能力。考虑到SPS在生产和致密大量材料方面的独特性能，基于Ti，CNT，Ni和WC之间以粉末，片状和纳米级形式组成的各种形式的反应，制备了复合材料作为三明治结构。管。首先将原材料按照从底部到顶部的Ni粉末，WC-10Ni，碳纳米管涂覆的Ti板，WC-15Ni和Ti板的顺序放置在石墨模具中。显微组织研究表明，镍粉层作为集成层已充分致密，第二层WC-Ni从底部附着到Ni层，在顶部附着在镍层上。_3种钛化合物。另外，通过与WC和CNT的反应，Ti片变为TiC颗粒，通过适当地结合结构，将WC-15Ni置于该层的顶部。最终，钛板保留在样品的顶部。样品的显微硬度检查显示，由于金属间化合物和碳化物的形成，与Ti基层位置有关的最高硬度。
