“…At interface between both diamond grits & brazing alloy, there is a tendency of Ti and Sn for segregation. TiC reaction layer has been formed as grains shape about 50 nm in size between both diamond grits & braze matrix, can relieve interfacial stress associated, this leading to promote strength of interfacial bonding as depicted in Figure 5 [33]. [In 2008 Klotz & et al] have investigated that reactions which occurred at interface between diamond & active brazing alloy, have a crucial effect in advancing and understanding tools performance, where active brazing alloys is an efficient technique to join diamond with metallic substrates.…”

This article surveys all researches which have conducted on polycrystalline diamond (PCDs) cutting tools, with particular consideration to the characteristics and performance of diamond-metal interface. There has been a revolution in industry over the fifty years or so, due to the usage of diamond in numerous applications, because of the special properties of diamond, joining diamonds to various materials by brazing requires much more precision than traditional brazing. Diamond is frequently utilized in cutting tools and workpieces because of its great hardness and wear resistance. Copper base filler & nickel base filler are the two materials that are most frequently used as brazing fillers in diamond brazing. This review describes the properties of diamond, how it interacts with metals and alloys, how it wets them, what influences these interactions, and how practical aspects of diamond joining is. Additionally, an analysis is done on a number of new brazing alloys, including amorphous Ni-based brazing filler metals.

“…For example, Tong et al [20] investigated the thermal distribution within the grinding wheel matrix during the ultrahigh-frequency induction brazing process by finite element simulation. Ma et al [21,22] conducted a brazing experiment of the diamond grains with high-frequency induction brazing technique; they reported that the metallurgical bonding occurred not only at the interface of diamond grits and brazing alloy but also at the interface of brazing alloy and steel substrate of tools. In addition, Li et al [23] indicated that the brazed CBN wheel produced by high-frequency induction brazing technique shows a good bonding strength during high-speed grinding of Inconel 718 superalloy.…”

In order to prepare monolayer brazed superabrasive wheels, the polycrystalline cubic boron nitride (PCBN) grains were brazed to AISI 1045 steel matrix with Ag-Cu-Ti filler alloy using the high-frequency induction heating technique. The compressive strengths of brazed grains were measured. Morphology, chemical composition and phase component of the brazing resultant around PCBN grain were also characterized. The results show that the maximum compressive strength of brazed grains is obtained in the case of brazing temperature of 965°C, which does not decrease the original grain strength. Strong joining between Ag-Cu-Ti alloy and PCBN grains is dependent on the brazing resultants, such as TiB 2 , TiN and AlTi 3 , the formation mechanism of which is also discussed. Under the given experimental conditions, the optimum heating parameters were determined to be current magnitude of 24 A and scanning speed of 0.5 mm/s. Finally, the brazing-induced residual tensile stress, which has a great influence on the grain fracture behavior in grinding, was determined through finite element analysis.
