چکیده انگلیسی
Using carbon fiber needled fabrics with Cu-mesh and graphite powder as the preform, Cu mesh modified carbon/carbon(C/C-Cu) composites were prepared by chemical vapor deposition (CVD) with C3H6 and impregnation-carbonization (I/C) with furan resin. C/C composites, as a comparison, were also prepared. Their microstructures and wear morphologies were observed by optical microscopy (OM) and scanning electron microscope (SEM), respectively. Wear behavior of C/C and C/C-Cu composites under different applied loads were investigated on a pin-on-disc wear tester. The results show that Cu meshes are well dispersed and pyrolytic carbon is in rough laminar structure. Both C/C and C/C-Cu composites had good wear properties. The current-carrying capacity of C/C-Cu composites increases and the arc discharge is hindered as the applied load increases from 40Â N to 80Â N. Both C/C and C/C-Cu composites had good wear properties. The mass wear rate of C/C-Cu composites under 80Â N was only 4.2% of that under 60Â N. In addition, C/C-Cu composites represent different wear behaviors because wear mechanisms of arc erosion, abrasive wear, adhesive wear, and oxidative wear are changing under different applied loads.
