| Research Abstract |
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.
