Embedding CNT’s in molten aluminum by mechanical stirring represents one approach of producing aluminum carbon nanotubes composites (Al-CNT’s). However, molten aluminum is known for its high surface tension with CNT’s resulting in extremely poor wettability. One approach to tackle this problem is done by metallizing CNT’s via electroless plating. The new interfacial metallic layer on CNT’s improves their dispersion and wettability with molten aluminum. One of the challenges, however, is the rapid growth of the plated layer on CNT’s resulting in aggregates of metal-coated CNT’s of a poor dispersion in molten aluminum making the industrial up-scaling of the process not viable. In this work, an approach to control the kinetics of the electroless reaction is presented by changing the catalyst concentration, the plating time and the volume of electroless solution relative to the amount of CNT’s. The influence of the plating process on the mechanical properties will be presented.
