一种NiAl金属间化合物基固体自润滑复合材料及其制备方法
摘要：
本发明涉及一种含有Ti3SiC2和C二元复合润滑相和增强相TiC的NiAl金属间化合物基固体自润滑复合材料的制备方法。NiAl金属间化合物基固体自润滑复合材料，其特征在于它由Ni粉、Al粉、Mo粉、Nb粉、Fe粉、B粉和Ti3SiC2粉制备而成，其中Ni∶Al∶Mo∶Nb∶Fe∶B的摩尔比＝48∶50∶1∶1∶0.5∶0.02，Ti3SiC2粉的加入量为Ni粉、Al粉、Mo粉、Nb粉、Fe粉和B粉总质量的5-20wt.％。本发明合成的NiAl/Ti3SiC2-C/TiC金属间化合物基固体自润滑复合材料的组份设计新颖(金属间化合物基体+复合润滑相+增强相)，致密度高、摩擦学性能好、工艺参数稳定，制备过程快捷简单，易操作，适用于制造高性能NiAl金属间化合物基固体自润滑复合材料。
摘要（英）：

The invention relates to a preparation method of a NiAl intermetallic base solid self-lubricating composite material containing Ti3SiC2 and C binary composite lubrication phase and wild phase TiC. The NiAl intermetallic base solid self-lubricating composite material is prepared from Ni powder, Al powder, Mo powder, Nb powder, Fe powder, B powder and Ti3SiC2 powder, wherein the molar ratio of Ni: Al: Mo: Nb: Fe: B=48: 50: 1: 1: 0.5: 0.02, and the addition quantity of the Ti3SiC2 powder is 5-20 weight percent of the total weight of the Ni powder, the Al powder, the Mo powder, the Nb powder, theFe powder and the B powder. The NiAl/ Ti3SiC2-C/TiC intermetallic base solid self-lubricating composite material synthesized by the method has novel component design (intermetallic matrix+ composite lubrication phase+ wild phase), high density, good tribological properties and stable technological parameters. The preparation process is fast and simple, and the method is easily operated and is suitable for preparing NiAl intermetallic base solid self-lubricating composite materials with high performance.
