dry ball milling and wet ball milling for fabricating

dry ball milling and wet ball milling for fabricating

Jul 04, 2018· Abstract. Yttria-reinforced copper matrix composites were prepared by dryball milling(DBM) and wetball milling(WBM), respectively, followed by spark plasma sintering (SPS). It is to determine which milling process is better for fabricating Cu–Y 2 O 3 composites. It is found that Cu–Y 2 O 3compositessynthesized by DBM exhibit better densification, mechanical and electrical properties …

Also, the CNTs were pre-coated to improve the agglomeration of the CNTs withcopper powder. The main aim of this work is the fabrication of Cu-CNT nanocompositepowderusing the MA byball milling. The as-received dendriticcopper powderschange their shape sequentially to flaky, disk-typed particles and finally, to globular type particles
