Synthesis of Cu-CNT nanocomposite powder by ball milling

Also, the CNTs were pre-coated to improve the agglomeration of the CNTs with copper powder. The main aim of this work is the fabrication of Cu-CNT nanocomposite powder using the MA by ball milling. The as-received dendritic copper powders change their shape sequentially to flaky, disk-typed particles and finally, to globular type particles.

Powder metallurgy – basics & applications

In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed. • Optimum diameter of the mill for grinding powders is about 250 mm Ball Mill

Sep 01, 2010· Sep 01, 2010· The XRD studies on ball milled iron powders showed that the diffraction peaks become substantially broadened after milling. The (1 1 0) Bragg peak of un-milled powder and that after 20 h of milling is shown in Fig. 1.This broadening can be attributed to reduction of crystallite size and introduction of defects (microstrain) because of milling process .
