METHOD FOR MAKING A COMPOSITE PRODUCT AND IN PARTICULAR A HEAT SINK |
摘要 |
The invention concerns a composite product comprising a matrix consisting mainly of a metal such as copper and ceramic (carbon, carbide or nitride) particles dispersed in the matrix. The method consists in preparing a homogeneous powder mixture containing mainly the metal and the ceramic particles, cold-pressing the powder mixture and the ceramic particles to obtain an intermediate product (8, 8') and densifying the intermediate product (8, 8') by at least a heat-process step, such as forging or hot rolling. The method is particular designed for the manufacture of heat sinks for electronic circuits. |
