The high-powered brazing diamond saw was developed to cut vehicle tyre
efficiently. The Ti-coated diamond and the uncoated diamond were brazed with NiCr
alloy by high-frequency induction under argon atmosphere at 1020℃ within 10
seconds. The interfacial microstructures between brazed diamond and the filler alloy
were analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD) and
energy dispersion spectrometer (EDS). It is surprisedly found that Cr-carbides forms
compactly and normally on the surface of Ti-coated diamond brazed, whereas Crcarbide
forms loosely and tangentially on the surface of uncoated diamond brazed.
The abrade experiment results for the brazed diamonds show that the bond strength
between the Cr-carbide and uncoated diamond brazed is lower than the normally
formed Cr-carbide and the diamond. Furthermore, the cause that Ti changes the
morphology of Cr-carbides on the surface of Ti-coated diamond brazed is discussed
by the further tests that are specially designed. |
