Carbon nanotubes (CNTS) have attracted increasing attention as an ideal reinforcement for metal matrix composites because of their remarkable physical and mechanical properties. However, achieving appropriate interfacial load transfer is the foremost concern for designing high-performance CNT/Al matrix composites. Accordingly, improvement in the mechanical performance of CNT/Al matrix composites is much lower than the theoretical expectations. In this work, a strategy of ceramic coating was developed to fabricate CNT/Al matrix composites with enhanced interfacial strength. The influence of surface ceramic coating on the CNT-Al interfacial morphology, interfacial strength, as well as on the tensile property of the CNT/Al matrix composites, were systematically studied.
