Cu-diamond composite are expected to combine the advantages of copper and diamond to achieve the performance of low density,high thermal conductivity,and low thermal expansion.Composite electrolytic deposition is a promising technique for preparing Cu-diamond composite.The influences of inter-sand process parameters towards diamond content and bulk density for composites were studied,and then the inter-sand process parameters were optimized.Cu-diamond composite with uniform distribution diamonds inside and a high bulk density were achieved under optimized inter-sand process parameters.The relationships between optimized inter-sand process parameters and diamond diameter were also simulated in this paper.
