测定了SiC颗粒/铝合金体系的结合过程和润湿性。SiC颗粒与铝液之间的润湿性通过颗粒掺入所需的时间来评价。掺入时间可以从搅拌时间-熔融温度图测量。镁和钛对SiC的亲和力强，缩短了α -SiC颗粒在铝液中的结合时间，改善了铝液的润湿性。铜和锌延长了结合时间，在基体中没有发现反应产物。此外，与SiC的亲和力弱的表面活性元素（铅和铋）极大地延长了掺入时间，因为这些元素阻止了界面处的反应，而锂显著缩短了掺入时间。
The incorporation process and the wettability for an SiC particles/aluminium alloy system were measured. The wettability between SiC particle and liquid aluminium was evaluated by the time required for the particulate incorporation. The incorporation time could be measured from a stirring time-melt temperature chart. Magnesium and titanium shortened the incorporation time of α -SiC particles into liquid aluminium and improved the wettability because of their strong affinity for SiC. Copper and zinc prolonged the incorporation time and no reaction products were found in the matrix. Furthermore, surface active elements with weak affinity for SiC (lead and bismuth) extremely prolonged the incorporation time because these elements prevent the reaction at the interface, whereas lithium shortened the incorporation time remarkably.
