Friction and Wear Properties of Copper/Carbon/RB Ceramics Composite under Electrical Current
Friction and wear properties of the copper/carbon/RB ceramics (Cu/C/RBC) composite were investigated under electrical current with and without arc-discharge. The weight fraction and the mean diameter of RB ceramics powder were 5 wt% and 4.9 μm, respectively, in the Cu/C/RBC composite. Frictio...
