- Abstract
- Kinetic and thermal spray processes were used to fabricate the multi-walled carbon nanotube (MWCNT) reinforced Cu composite coatings with 0-1.0 wt% MWCNTs. The microstructures of the composite coatings were analyzed and electrical and mechanical properties such as the electrical resistivity, microhardness, wear rate, and friction coefficient were evaluated. Since the deposition and microstructural evolution mechanisms of kinetic and thermal spraying are entirely different, the characteristics of the spray processes dominated the microstructure and interface of the Cu matrix, MWCNT structure, and the nature of the interface between MWCNTs and the Cu matrix, which are correlated with the properties. In this study, the relationship among electrical and mechanical properties with (MWCNT) state and the microstructural factors of the MWCNT/Cu composite coatings were investigated via microstructural and physical metallurgical analyses.
