摘要： 采用微波烧结方法制备出CuTi-金刚石复合体，并对复合体的工艺、组织和结构进行了研究．结果表明，金刚石颗粒在烧结过程中没有发生石墨化转变，CuTi-金刚石复合体中金刚石颗粒与CuTi基体间能形成良好的结合．CuTi-金刚石复合体的致密度随金刚石含量的增加出现先增加后降低的变化趋势，当金刚石含量为18.75～25vol％时达到最大值．

Abstract: CuTi-Diamond composite was first made by microwave sintering. The process and structure of the composite was studied. Results show that graphitization of diamond was not observed during sintering at 950℃. Diamond bonds well with CuTi matrix. The density of composite increases initially as the diamond content increases and then decreases after passing a maximum at the diamond volume content of about 18.75~25vol%.

Key words: microwave sintering, composite, diamond, CuTi
