Notes:
An experimental study on induction brazing diamond grinding wheel with Ni-Cr filleralloy was carried out. Brazing trial was conducted at the temperature range of 1020-1080 oC and thebrazing time were 10, 20, 30 and 40 seconds in a flowing argon environment with a flow rate of5000cm3/min. The scanning electron microscopic (SEM) results indicate that good wetting existedbetween the brazing alloy and diamond. The element distribution of C, Cr, Si and Ni were examinedby energy dispersive spectrometer (EDS), the results demonstrated an intermediate layer rich in thechromium formed between the filler metal and diamond. Kinds of compounds formed in the interfacewere detected by means of x-ray diffraction (XRD), and the graphitization of the brazed diamond gritswas determined by Raman spectroscopy. The monolayer induction brazing diamond grinding wheelswere used in grinding of nature granite, experimental results show that induction brazing wheelsperformed better than vacuum brazing diamond wheels, and no pullout of diamond grits or peeling ofthe filler metal layer took place
