With the correct compound designing, a composite layer with thickness of 3 to 4 millimeters was formed on the surface of cast iron by means of cast-sintering technique.
Microstructure of the composite layer was researched with the help of optical microscope, scanning electronic microscope (SEM), electronic probe microanalysis (EPMA) and x-ray diffraction (XRD). The compacting mechanism of the billet and the forming mechanism of the reinforcement were studied based on thermodynamics a...
