SiC_P增强泡沫铝基复合材料制备工艺及润湿性研究

Fabricating Process of SiC Particle-Reinforced Aluminum Foam Matrix Composite and Its Wettability

对采用熔体发泡法直接制备碳化硅颗粒增强泡沫铝基复合材料进行了探索 ,讨论了制备过程中SiCP 与铝液间的润湿性、发泡工艺参数与温度控制等对制备工艺的影响。表明该工艺简单 ,易于操作 ,不需任何增粘措施 ,处理后的SiCP 浸润性好且分布均匀 。

The SiC particle reinforced aluminum foam matrix composite produced by the melt route foam process was studied. The factors such as the wettability between SiC P and liquid aluminum, control of foaming process and temperature to have influence on the technological process for preparation were discussed. The results show that the foaming process is controlled easily without adding the viscosity increasing agents, and the spatial distribution of SiC P being treat and distribution of closed cells can be improved.
