摘要: In this paper, friction and wear properties of nano-carbon reinforced Cu/Ti3SiC2/C nanocomposites are evaluated by orthogonal experiment method. The primary and secondary order of factors affecting wear characteristics of the nanocomposites and the best working conditions of specimens are obtained by means of range analysis and variance analysis. Results demonstrate that change of graphene nanoplatelets (GNPs) content has a very small effect on friction and wear properties of the nanocomposites under the premise of total content of GNPs and multi-walled carbon nanotubes (MWCNTs) is 1 wt.-%. Under these experimental conditions, the optimal level is that content is GNPs 0.8 wt.-% and MWCNTs 0.2 wt.-%, load is 350 N and rotational speed is 50 r x min(-1). Microscopic analysis shows that the additions of graphene nanoplatelets and multi-walled carbon nanotubes help to improve wear resistance of the nanocomposites. Main wear mechanisms of the nanocomposites are abrasive wear, delamination wear and oxidation wear.
