Effect of CNFs content on the tribological behaviour of spark plasma sintering ceramic-CNFs composites

► CNFs/ceramic nanocomposites were densified by spark plasma sintering. ► The tribological properties have been investigated as a function of CNFs content. ► Low wear resistance of CNFs material and CNFs/ceramic nanocomposites have been found. ► The friction coefficient of the nanocomposites with high CNFs content was very low.
