More Information
Summary:The invention discloses a high-toughness high-wear-resistance nickel-copper-based diamond composite material as well as a preparation method and application thereof. The composite material comprises 75-95 vol.% of nickel-copper alloy binding phase powder and 5-25 vol.% of diamond powder. The composite material is obtained by weighing required nickel-copper alloy binding phase powder and diamond powder according to a preparation ratio, mixing by adopting an acoustic resonance method, and carrying out hot pressed sintering after pre-pressing deformation. The technological process is simple, the production period is short, the production cost is reduced, dangerous operation such as a mechanical ball milling method is not involved, the composite material is suitable for industrial production, the prepared composite material has high bending strength, impact toughness and wear resistance, and when the composite material is used as a raw material of drilling tools, tools and molds and grinding tools, the service li
