Abstract
Brazing of diamond to steel substrate using Ni-based filler alloy encounter several challenges like inferior joint strength and conversion of diamond to graphite. To overcome the problem, the present study tries to braze diamond to steel substrate using an Ag-based filler alloy. Two different weight percentages of an active element, titanium, were added to the Ag-based filler alloy to improve its wetting ability, i.e. 2 and 10 wt%, on the surface of the synthetic diamond grit. The characteristic quality of the brazed joint was subsequently inspected using a high-resolution electron microscope. Filler alloy containing 2 wt% of Ti as an active element showed better results in terms of grit retention ability compared to other combination of Ag-based and Ni-based alloy.
