The CNTs were ball milled before adding to the melt. Although there was grain refinement in the metal matrix, the lack of interaction between the metal matrix and reinforcement was reported by this method. Alekseev et al. 38 investigated the effect of CNTs on the mechanical properties of cast Al, grade A5. Significant improvement in the ...
The aim of the paper is to investigate the effect of size of multiwalled carbon nanotubes (MWCNTs) as additives for dispersion in gear oil to improve the tribological properties. Since long pristine MWCNTs tend to form clusters compromising dispersion stability, they are mildly processed in a ball mill to shorten the length and stabilized with a surfactant before dispersing in lubricant.
material, which was ball milled for 5 and 10 hours. NanocylTM NC7000 is an asgrown material produced in an industrial largescale chemical vapour deposition process.
