Amorphous porous silica particles, originated from rice husks, were dipped into surfactant solutions including un-bundled CNTs. It existed on the surface and also inside the pores. By using as a reinforcement of the sintered magnesium (Mg) materials, these compounds were mixed with Mg powders. The tribological and microstructural behavior of sintered Mg composite material reinforced with Mg_2Si-CNTs compounds were evaluated. As a result, both the bearing effect by CNTs and the wear resistance by Mg_2Si hard particles were effective to improve the tribological properties of the sintered Mg composite.

将源自稻壳的非晶多孔二氧化硅颗粒浸入含有未捆绑碳纳米管的表面活性剂溶液中。它既存在于表面，也存在于孔隙内部。将这些化合物与镁粉混合，作为烧结镁（Mg）材料的增强剂。研究了Mg_2Si-CNTs增强烧结Mg复合材料的摩擦学和微观组织行为。结果表明，CNTs的承载作用和Mg_2Si硬质颗粒的耐磨性都能有效改善烧结Mg复合材料的摩擦学性能。
