摘要

以WO₃、Mg和金刚石粉为反应体系,NaCl为稀释剂,采用自蔓延高温合成技术制备金刚石表面钨层。通过调控NaCl含量实现绝热温度变化,并系统研究其对金刚石表面钨层覆盖率及钨层厚度的影响。结果表明：金刚石表面钨层的覆盖率及厚度随绝热温度升高而增大。在WO₃、金刚石、Mg、NaCl质量比为1:0.53:0.34:0.13的条件下,绝热温度达到3 569 K时,可获得覆盖率约为82%、厚度约为340 nm且分布均匀的钨层。而且自蔓延高温合成特有的瞬时高温-快速冷却特性,能有效提高金刚石的稳定性,因此未观察到明显石墨化。

Abstract

The tungsten layer on the surface of diamond was prepared using WO₃, Mg, and diamond powders as the reaction system and NaCl as the diluent by the self-propagating high-temperature synthesis technology. The adiabatic temperature change was achieved by regulating the NaCl content, and its effects on the coverage radio and thickness of the tungsten layer on the diamond surface were systematically studied. The results show that the coverage radio and thickness of the tungsten layer on the diamond surface increase with the increasing adiabatic temperature. Under the condition that the mass ratio of WO₃, diamond, Mg, NaCl is 1:0.53:0.34:0.13, when the adiabatic temperature reaches 3 569 K, a tungsten layer with a coverage radio of approximately 82%, a thickness of approximately 340 nm and uniform distribution can be obtained. Moreover, the unique instantaneous high-temperature-rapid cooling characteristic of self-propagating high-temperature synthesis effectively improves the stability of diamond, and therefore no obvious graphitization is observed.
