利用SHS技术制备金属陶瓷局部复合铸钢基材料的研究

Study on Base of Composite Steel Castings of Cermet Part by SHS Technology

本文将SHS技术与铸造技术相结合,制备了TiC/Ni和TiC/Ni基自熔合金陶瓷局部复合的铸造钢基材料。用金相显微镜分析了金属(合金)材料的显微组织结构及陶瓷与基材的界面结构,并进行了硬度与冲击韧度试验。结果表明,试验所获得的金属(合金)陶瓷与低合金钢基材之间为冶金结合,金属(合金)陶瓷具有良好的硬度和冲击韧度,有望在小能量冲击工况下得到应用。

Combination of SHS with Pouring Process,TiC-Ni and TiC-Ni alloy Cermet in the part of cast steel-based material have been produced.The cermet microstructure and interfacial structure between cermet and matrix material have been inspected with optical microscopy,the hardness and impact test has been done,resulting in metallurgical joins existed in both.With excellent hardness and impact toughness cermet can be applied to situation with a little energy impact.
