摘　　要：通过改进工艺参数实现了Cu对SiCp预制型的无压渗透。渗透样块可分为亮色Cu基体区、深黑色渗透区和浅黑色SiC预制型区三部分。分别用X射线衍射仪、扫描电镜和能谱仪对相关试样渗透层的物相、表面形貌和元素分布进行分析,分析认为渗透是在毛细管力和负压机制共同作用下完成。The pressureless infiltration of SiCp/Cu has been achieved by improving the process parameters. The infiltrated sample can be divided into three parts：bright Cu matrix area,dark black infiltrated area and flat black SiC perform area. The phase,surface topography and elements distributing of the infiltrated layer of the interrelated sample were studied by X-ray diffractometry,scanning electron microscopy and energy spectrometer,and the infiltration was drived by capillary force and negative pressure.
