Abstract

A slight decrease in average friction coefficient and a great decline in volume loss (reaching to 63.1%) have been obtained from TiNi matrix composites prepared by sintering 1 vol.% multi-walled carbon nanotubes (MWCNTs) with Ti and Ni elemental powders. It is considered that in situ TiC and the remaining MWCNTs act as reinforcements and plays the major role in the improvement. This study explores the possibility of developing novel TiNi matrix tribocomposites.
