| Abstract: | The research and development of preparation processing of nanosize cemented carbide are reviewed. The merits and drawbacks of two different ways of producing nanosize powder are compared, and the spray conversion processing is introduced in detail. The experimental data show that the type of grain growth suppressor and the way in which the suppressor is added have a great influence on grain growth. Finally a popular sintering processing and advanced plasma activation sintering and microwave sintering techniques are addressed. |
