With the correct compound designing, a composite layer with thickness of 1.5to 6 millimeters was formed on the surface of casting by means of Cast-sintering technique.
Microstructure of the composite layer was analyzed with help of optical microscope, scanning electronic microscope(SEM), electronic probe microanalysis(EPMA)and X-ray diffraction(XRD).The compacting of the billet and the forming mechanism of the carbide reinforcement were studied based on thermodynamics and kinetics of ...
