Abstract:
To obtain a strong interfacial bonding between carbon nanotubes (CNTs) and zinc (Zn) matrix has always been a crucial issue for the preparation of high-performance CNTs-Zn composites. In the present study, a hot-pressed sintering process is used to fabricate the 27wt% Al-containing Zn alloy composites with different amount of CNTs. The tensile strength and ductility are simultaneously improved by the addition of CNTs. The results of the interface characterization also indicate that the in-situ formed carbides, ZnC8, are formed between CNTs and Zn matrix. These carbides can lock the dispersed CNTs in place and improve the CNTs-Zn interface bonding. This study provides a novel approach to improve the load transfer efficiency of CNTs for fabricating CNTs reinforced Zn composites with high performance.
