【摘要】 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,孔洞分布均匀。更多还原

【Abstract】 The SiC particle-reinforced aluminum foam matrix composite produced by the melt route foam process was studied. The factors such as the wettability between SiCP and liquid aluminum, control of foaming process and temperature to have influence on the tech-nological 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 SiCp being treat and distribution of closed cells can be improved.更多还原
