Composite plated diamond and production process thereof

The invention discloses a production process of composite plated diamond. The production process comprises a surface impurity removal process, a micro-evaporation titanium plating process, a point discharge barrel nickel thorn plating process and a chemical nickel thorn ball plating process, after the surface is coated with titanium, electroplating and chemical plating are carried out, thick and strong nickel thorns and nickel balls are formed, the holding force between the nickel thorns and the nickel balls and a binding agent is increased, diamond/CBN is prevented from falling off, the obtained composite plated diamond meets the use requirement of a resin binding agent and also meets the use requirement of ceramic and metal binding agents, meanwhile, the interface binding force between the diamond/CBN and the binding agent is improved, and the service life of the composite plated diamond is prolonged. The service life of the grinding wheel made of the ceramic bonding agent is prolonged by more than 15% unde
