Attrition Milling of CNT and Dispersion in Mg Alloy Matrix by Friction Stirring Process

Abstract:

Effect of attrition milling and subsequent ultrasonification of CNT on dispersion in ethanol was investigated. An attempt was also made to disperse the CNT in Mg alloy matrix by solid state friction stirring process for fabrication of metal matrix composite. Attrition milling was performed at a rotation speed of 700rpm for various times up to 6 hour. After 2 hours of milling, amorphous trace was observed in X-ray diffraction pattern. Attrition milling and subsequent ultrasonification enhanced dispersion of CNT in ethanol. Mg alloy matrix composite dispersed with the CNT was successfully fabricated by friction stirring process. The CNT-dispersed composite was analyzed by optical microscopy and Vickers hardness.
