Research on Thermodynamic Mechanism of Diamond Surface Metallization

The wetting of diamond by three kinds of liquid alloy and its surface metallization by means of solid contact techniques were systematically studied. The micro structure of the surface-metallized diamond in the matrix alloy as well as its chemical compositions distribution were investigated by SEM analyses X-ray diffraction, were used to observe the phase structure of the carbides formed on the diamond surface. Also, the thermodynamic mechanism for the formation of the carbides was preliminarily discussed.
