Abstract
- Abstract: The wettability and interfacial reactivity between diamond and matrix are of great importance to their bonding strength and the applications, but the relating investigations are scarce. In this paper the wettability and interfacial reactivity in diamond–borosilicate glass system were studied by wettability measurements, thermogravimetry, scanning electron microscope, X-ray diffraction and Raman spectra. Results show an excellent wettability of the diamond by the borosilicate glass melt at temperatures above 700°C. A distinct expansion with many irregular pores can be found in the diamond–borosilicate glass composites sintered above 800°C, which caused by the oxidation of the diamonds. The start oxidation temperature of the diamond in the composites is 817.7°C. So the quite compact bulk composites can be obtained below this temperature. [Copyright &y& Elsevier]
