Alternatively, ball impact treatment (BIT) can be used to Al/CNT plating on Al substrates. This method has been applied by using planetary ball mills and vibratory ball mills. For example, Romankov et al. [10] successfully used mechanical alloying (ball impact treatment) to obtain intermetallic coatings TiAl in a vibratory ball mill.

Elemental powders of Al, Cu, Mg and x wt.% CNT (x: ) were blended and milled in the highenergy ball mill for 4 h. Milled powders of Al alloyCNT composites were subsequently consolidated by upset forging followed by hot extrusion. Even though the particle size of milled powders of Al alloyCNT composites decreased with the addition of CNT, there is no significant effect on crystallite ...
