Morphology Analysis of Mixed Powder: Cu-Coated Graphite, Copper, and Cr2AlC

In Figure 1 (b), the morphology of the mixed powder is presented, revealing that the Cu-coated graphite particles possess a flake-like structure with a uniformly and thoroughly coated Cu layer. Meanwhile, the pure copper particles adopt a spherical shape, in contrast to the lamellar morphology of the Cr2AlC particles.
