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