Abstract: In this study, Ag-Cu-Zn brazing alloy together with Cr or Ti powder had been used to braze diamond grits under different environments, such as: air, vacuum, argon gas protection, salt covering and carbon powder covering. The microstructure on the interfaces of diamond grits, brazing alloy and steel substrate was examined by Scanning Electron Microscopy (SEM) and optical microscopy. The results showed that by adding Cr powder, the diamond grits could be brazed onto the steel substrate in air and owned enough bonding strength and wear resistance when grinding granite. By adding Ti powder, the diamonds could be well brazed in vacuum or in the air with the protection of carbon powder. In brazing, the migration of Cr or Ti element to the surface of diamond and the forming of Cr or Ti rich area had significantly improved the wettability of the brazing alloy to the diamond grits.
