Fabrication of Fe-Based Al2O3-TiC Ceramic/Steel Composite by Self-Propagation High-Temperature Synthesis

摘要：

　　The Fe-Based Al2O3-TiC Ceramic Composite was fabricated by combining the methods of Self-propagating High-temperature Synthesis with casting.The microstructures of ceramic layer and interface were characterized via SEM,EDS and X-ray diffraction.The Results show that the microstructure of ceramic layer is dense,and the in-situ Al2O3 and TiC particles with size of 1-2 μm are distributed on the ferrite matrix.The hardness of compact ceramic layer reaches 48HRC,and it has graded distribution from ceramic layer to the ferrite matrix.The composite interface between ceramic and matrix is compact,and takes on flexuous.The composite material bonds in a metallographic manner,with high bonding strength.
