Abstract
In this paper, cold spray in conjunction with powder ball milling was used to fabricate GNP-reinforced copper MMC coatings without crossing materials' melting points. As a result, non-agglomerated and uniformly-distributed GNPs were included in the cold sprayed MMC powders and coating. No phase change and oxidation occurred during the coating fabrication. The friction coefficient of GNP-reinforced MMC coating reduced by approximately 20% compared to bulk copper. The cold sprayed MMCs also resulted in lower friction coefficient than spark plasma sintered MMCs.
