摘　　要：利用爆炸压制法压实钢结硬质合金粉末,采用低真空液相烧结扩散复合法将压实后的钢结硬质合金粉末与碳钢成功复合,制得TLMW50／碳钢复合材料。利用EDS、SEM和电子拉伸试验机对TLMW50-碳钢复合过程及界面结合强度进行研究和测试,结果表明:在1350℃真空液相烧结过程中,钢结硬质合金粉末中各元素及硬质相分解出的C、W元素在烧结时相互扩散;钢结硬质合金TLMW50／碳钢试样复合界面的结合强度值与钢结硬质合金TLMW50本身的相应力学性能接近,界面复合状况良好。The steel-bonded cemented carbide powder which being compacted by explosive compaction was bonded to carbon steel by lower-vacuum liquid phase sintering and element diffusing. The composite of TLMW50-carbon steel was obtained .The composite process analyzed by SEM and EDS and electronic tensile test showed that the C or W from hard phase and the element from the metal powder diffused each other in the liquid phase vacuum sintering process at 1350℃ and a good composite condition was found. the interface banding strength of TLMW50-carbon by electronic tensile tester was close to steel-bonded cemented carbide TLMW50＇s tensile strength.
