Cu coated graphite
WebAn SEM micrograph of pristine Al 2 O 3 and Cu–Al 2 O 3 powder are shown in Figure 4a,b, respectively, showing a uniform Cu coating on the alumina surface. The dispersion of the filler is improved as compared to pristine alumina powder. The Cu-coated Al 2 O 3 particles exhibit fine-scale roughness, characteristic of metal coating [22,23]. WebOct 25, 2024 · Firstly, Cu-coated graphite particle can weaken the mechanical hammering effect of Al 2 O 3 particles, and thus it is difficult to obtain the plastic deformation of copper particles. Secondly, the limited wettability among Cu-coated graphite, Al 2 O 3 and copper particles leads to a poor interface bonding.
