Microstructure and Hardness of Surface Composite Layer Fabricated by Evaporative Pattern Casting Technology

Abstract:

Surface composite layer was fabricated on the cast steel matrix using the evaporative pattern casting (EPC) technology. The pre-coating with WC and Cr-Fe particles as raw reinforcements was reacted with matrix and formed the composite layer. Then, the microstructure and hardness of surface composite layer were investigated by Scanning Electron Microscope (SEM), Olympus Microscope (OM), Energy Dispersive X-ray Spectroscopy (EDAX) and Rockwell Apparatus. The results show that the composite layer can be divided into transitive layer and penetrated layer, and the component analysis shows that the microstructure distribution of the penetrated layer is homogeneous.
