放电等离子烧结(SPS)是先进的基于 ON- OFF 直流脉冲电场活化和压力活化的烧结技术。文章综述了发现碳纳米管在 SPS 直流脉冲电场作用下以兆帕量级的压力可以部分相变为金刚石的过程；然后揭示了碳纳米管、富勒烯、石墨烯在直流脉冲电场作用下的热稳定性和相变为金刚石的机理；接着综述了实验条件参数对 SPS 金刚石合成的影响，以及采用 SPS 所合成的金刚石制备得到的金刚石/铜复合材料。最后，对 SPS 这种合成金刚石的新技术的未来前景进行了展望。

Spark plasma sintering (SPS)is an advanced sintering process based on the ON-OFF DC pulse electric field activation and pressure activation.The discovery of the process in which the Mpa scale pressure of CNT(carbon nano tube)under the SPS DC pulse electric field effect can partially phase into diamond has been summarized in this ar-tical.Then the thermostability and machenism of phase change of CNT,fullerene and graphene into diamond have been revealed.Then the influence of experimental condition parameters on the SPS diamond synthesis has been summarized and the diamond/copper composite prepared by diamond synthesized through SPS technique has been introduced. Finally,the perspective of this new technique of diamond sythesis by SPS process has been predicted.
