Carbide Tools Microwave Sintering

Carbide tools microwave sintering is a new type of carbide tools sintering technology It is significantly different from conventional heating methods. By interaction with the microwave ,microwave sintering sintered material inside atoms, molecules or ions kinetic energy increases, so the sintered material decreases the activation energy, the diffusion coefficient is increased, enabling low temperature rapid sintering, i.e. fines already too late to grow by sintering, is an effective means to create fine-grained materials.

Microwave sintering mechanical properties significantly better than conventional sintering. Microwave sintering has several advantages: significant reduction in the sintering temperature up to 500 ℃; reduce energy consumption; shorter sintering time and increase density, grain refinement. But the microwave sintering process prone to thermal runaway effect, the sintered body is heated unevenly, thus affecting product performance. Another high-power microwaves for industrial production in the manufacturing of great difficulty, microwave sintering can not be used for large-scale production.
