摘要
研究了WC -Co、铸造碳化钨硬质合金的淬火及深冷处理等热处理工艺 ,分析了WC -Co、铸造碳化钨硬质合金的金相组织 ,分析了WC -Co、铸造碳化钨硬质合金淬火和深冷处理提高性能的原因。研究了淬火和深冷处理提高性能的机理。结果证实WC -Co硬质合金金相组织为γ′和M7C3 、M6C、M2 3 C6型化合物 ,铸造碳化钨硬质合金金相组织为 η和M7C3 、M6C、M2 3 C6型化合物。淬火及深冷处理能强化粘接相 。
In this paper, we studied the quenching and cryogenic treatment processes of WC - Co and founding tungsten carbide cemented carbide, and analyzed their microstructure and the cause of increased performance of these treatment as well as the mechanism of increased performance of these treatment. It is conformed that the microstructure of WC - Co cemented carbide is γ′ and M 7C 3, M 6C, W 23 C 6 carbide and founding tungsten carbide is η and M 7C 3, M 6C, M 23 C 6. The adhesive phase can be strengthened and the histology and the microstructure can be improved by quenching and cryogenic treatment.
