Abstract
Diamond-WC-based cemented carbide composites were prepared by microwave hot-pressing sintering and microwave cold-pressing sintering. Density and hardness of samples were measured to determine the mechanical properties of the composites. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were adopted to characterize the microstructure and phase structure. Energy dispersive X-ray spectrometer (EDX) was used to evaluate the composition of the samples. The results indicate diamond-WC-based cemented carbide composites with excellent performance could be produced by microwave sintering, and samples fabricated by microwave hot-pressing sintering exhibit higher density and hardness, more homogeneous microstructure and diamond distribution compared to the microwave cold-pressing sintered samples.
