Nucleation and Growth of Cr7c3 of Brazing Diamond with Ni-Cr Alloy in Protective Atmosphere Furnace

摘要：

Mono-crystal diamond was brazed with Ni-Cr alloy in protective atmosphere furnace,SEM and XRD were used to analyze the carbides on the surface of diamond and the phases of diamond after brazing,respectively.The results show that the diamond brazed in protective atmosphere furnace can realize high strength connection;the diamond has clear edges and complete morphology after brazing.On the surface of diamond,the arrangement of Cr3C2 is regular,the growth direction of Cr3C2 has a certain orientation relationship with the(111)crystal plane of diamond,all the Cr7C3 nucleates and grows on the surface of Cr3C2,finally,the inner layer is regular arrangement Cr3C2 and the external layer is Cr7C3.
