Diamond/metal composite materials mainly cover diamond/copper, diamond/aluminum and diamond/titanium composites, among others. As a high-performance advanced material, diamond/copper composite is fabricated by compounding diamond particles with copper or copper alloy matrix. It features high hardness, excellent electrical conductivity and outstanding thermal conductivity, and holds great application prospects in mechanical processing, electronic packaging, automobile manufacturing, aerospace, national defense and military industries.
There are multiple fabrication techniques for diamond/copper composites, such as double coating treatment, powder metallurgy, infiltration process, ultrasonic additive manufacturing, electroplating, high temperature and high pressure method, as well as plasma sintering. Traditional preparation methods commonly suffer from obvious drawbacks, including uneven dispersion of diamond particles and weak interfacial bonding strength. The double coating method works by first plating carbide on diamond surfaces, followed by electroless copper plating to complete production. This technique is well-suited for manufacturing high-performance diamond/copper composites, and is expected to be widely adopted in mass production in the coming years.
With extensive application value, diamond/copper composites can be applied in diverse scenarios. In mechanical processing, they are ideal for making drill bits and high-precision cutting tools. In the automotive industry, they can be processed into various auto parts. For aerospace engineering, they serve as premium heat dissipation components for spacecraft parts under high thermal load.
