Preparation and Heat Treatment of Ni60-WC/Cr12MoV Bimetallic Composite Materials

摘要：

　　In present work,bimetallic composite materials (BCMs) were prepared by one-step sintering in box-furnace followed by quenching in salt furnace.The morphology and mechanical properties of the fabricated BCMs were characterized systematically.The results showed that Ni60-WC/Cr12MoV BCMs with a typical transition zone of ~480 μm could be successfully prepared by sintering at 1120 ℃ for 15min followed by furnace cooling to 400 °C and air cooling to ambient temperature.The resultant samples were heat treated by preheating at 860 ℃,heating at 1020 ℃,quenching at 520 ℃,and tempering for two times at 200 ℃ for 2h.The average micro-hardness of the BCMs was measured to be of 869.34,755.44~413.68,and 758.02 HV,which corresponded to the parts of Ni60-WC,transition zone and Cr12MoV,respectively.The interface binding strength of the BCMs was 234.22 MPa.
