Abstract
Powder metallurgy magnesium matrix composite reinforced with un-bundled carbon nanotubes (CNTs) and Mg₂Si/MgO hybrid compounds were prepared by solid-state synthesis between magnesium powder and amorphous silica particles including CNTs. Their tribological properties were investigated by using the ball-on-disc wear test equipment under dry sliding conditions. The friction coefficient of the composite material was low and stable because of no adhesion and stick-slip phenomenon in contacting with the SUS304 stainless steel ball as a counter material. This was due to both the defensive effect of hard Mg₂Si dispersoids and the self-lubricant effect of network nanotubes on the sliding surface.
