Abstract

Abstract

To study the influence of self-propagating process on the performance of diamond grinding head, high-frequency induction heating was used to induce self-propagating systhesis of Al, Ti, Cu, Ni and Sn powder and produce the heads.Microstructure of the heads and the bonding interface between diamond and metal matrix were analyzed.Grinding experiments were implemented to study the performance of heads.Resultsshow that high-frequency induction helps to reduce the pre-heating time and reaction time, thus increasing efficiency, and that Ni is a key element without which the reaction could not start.It is also found that diamond grains bond well with metal bonds, and that C and Ti diffuses and aggregates across the interface.In conclusion, the comprehensive processing performance of diamond grinding head is the best when the mass fraction of Al+Ti is 32%.
