摘要
在传统的钨钴类硬质合金(WC-Co)中掺杂一些特定的碳化物、氮化物、氧化物、稀土等,可以改善硬质合金的性能。添加一定量含Ti元素的化合物,可以一定程度上改善材料的硬度、韧性、抗腐蚀性等性能。阐述了近年来有关含Ti元素硬质合金的研究现状,包括制备工艺、微观结构分析和改性研究等,总结了当前研究含Ti钨钴类硬质合金的主要结论和趋势,并指出了含Ti板状晶硬质合金所具有的研究前景。
Doping some specific carbides,nitrides,oxides,rare earths,in the traditional WC-Co cemented carbide can improve the performance of the cemented carbide.Adding a certain amount of compound containing Ti element can improve the hardness,toughness,corrosion resistance and other properties of the material to a certain extent.The current research status of Ti-containing cemented carbides in recent years were reviewed,including preparation technology,microstructure analysis and modification research,and the problems in the development of Ti-containing cemented carbides and future research directions were pointed out.
