Abstract
The friction and wear behavior of multi-wall carbon nanotube (MWCNT)-reinforced Ti composite were evaluated under dry sliding conditions. Ti powders were immersed in suspended 3.0wt.% MWCNTs in a zwitterionic surfactant solution to prepare the composite. To eliminate the solid zwitterionic substance, coated Ti powders were heated at 873 K for 3.6 ks under a mixed H₂/Ar gas atmosphere. Coated Ti powders were mixed with pure Ti powders at ratios of 0, 20, 50 and 100 in wt.%. Spark plasma sintering and hot compression were applied to consolidate the mixed powders. Subsequently, a ball-on-disk test was carried out at a rotational speed of 120 rpm with different applied loads of 0.98, 1.96 and 2.94 N by using 304 stainless steel balls as a counter material. The friction coefficient of each specimen decreased with increasing MWCNT content and applied load.
