摘要：

In this work multiwall carbon nanotubes (MWCNTs) reinforced 8 mol.% yttria-stabilized zirconia (8YSZ) composites were prepared using attrition milling and spark plasma sintering (SPS, at 1400 degrees C) in different compositions (0, 1, 5, 10 wt% MWCNTs). The effect of sliding speed at low (V1 = 0.036 m/s) and high (V2 = 0.11 m/s) values has been investigated. Outstanding wear improvement at both low/high sliding speed has been reported with the addition of 1 wt% of MWCNTs. This was most likely attributed to two main factors: 1) the formation of a perfectly continuous and uniform tribo-film. 2) the improved flexural strength, fracture toughness and density.
