Research on Thermodynamic Mechanism of Diamond Surface Metallization

摘要: 本文较系统地研究了三类液态合金对金刚石的润湿和固相接触法实现的金刚石表面金属化。用SEM分析了胎体合金中金刚石表面金属化的微观组织结构、化学成份分布；用X射线衍射确定在金刚石表面形成碳化物的相结构，并对碳化物形成的热力学机制进行了探讨。

Abstract: 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.
