摘要
在烧结温度为1350℃时,采用液相烧结法将爆炸压实后的钢结硬质合金粉末复合在碳钢表面,获得了覆层材料。对界面的组织及性能进行测试,结果表明:界面过渡区的组织为珠光体,有新相M23C6、Fe3W3C生成,剪切强度为106MPa,在覆层/碳钢的界面结合处,存在有覆层的高硬度到钢基体低硬度的狭窄过渡区。
Steel-bonded cemented carbide powder processed by explosive compaction was bonded to the surface of carbon steel through liquid phase sintering under 1350℃. The microstructures and propertie of interface were analyzed, The results showed that： the shape of the interface structure are pearlite, the interface obtained M23C6、Fe3W3C, shear strength achieved 106MPa, in the vicinity of the bonding interface, there exists a narrow transitional zone from high hardness to low hardness between cladding and carbide steel.
