摘要: 碳化硼是一种重要的特种陶瓷材料,具有低密度(2.52 g/cm3)、高熔点(2450˚C)等优异的物理化学性能。但由于其烧结温度过高、难以致密化及韧性低等缺点,限制了它的应用。针对该问题研究通过非均相沉淀法制备了兼具B4C结构陶瓷超轻高强与Cu/Ni合金优良抗生物污损两大优势性能的Cu/Ni增韧B4C基陶瓷–金属复合材料。探究了B4C表面预处理、溶液中金属离子浓度、Cu/Ni在复合粉体中比例因素对复合粉体中Cu/Ni对B4C的包覆的影响。此外,简单地分析了烧结温度对Cu/Ni-B4C金属陶瓷复合材料的致密化程度的影响。

Abstract: Boron carbide (B4C) is an important ceramic material with excellent physical and chemical properties, such as a low density (2.52 g/cm3) and high melting point (2450˚C). However, its two major drawbacks are the low fracture toughness and the very high sintering temperature for pure boron carbide ceramics, which restrict its application. To handle with the weakness, B4C coated by Cu/Ni alloy was prepared by homogeneous precipitation preparation method in this paper. This kind of composite material had both advantages of B4C and Cu/Ni alloy. Effects of B4C surface pretreatment, metal ion concentration in the starting solution, Cu/Ni composite powder in proportion of composite powder on the rate of coverage were investigated. What’s more, the effect of sintering temperature on Cu/Ni-B4C metal ceramic composites was also analyzed.
