Aluminum and Nickel Matrix Composites Reinforced by CNTs: Dispersion/Mixture by Ultrasonication

Abstract: The main challenge in the production of metal matrix composites reinforced by carbon nanotubes (CNTs) is the development of a manufacturing process ensuring the dispersion of nanoparticles without damaging them, and the formation of a strong bond with the metallic matrix to achieve an effective load transfer, so that the maximum reinforcement effect of CNTs will be accomplished. This research focuses on the production by powder metallurgy of aluminum and nickel matrix composites reinforced by CNTs, using ultra… Show more

“…MMNCs are good candidates for wide use in components for various sectors, such as the automotive and aerospace industries [3,4]. Ni [3,4,5,6], Cu [7,8,9,10] and Al [11,12,13,14] represent the materials most commonly studied as matrices of these nanocomposites, due to the nanoreinforcements’ strengthening potential, thus becoming advantageous alternatives to conventional materials. Among the various nanoreinforcements investigated, carbon nanotubes (CNTs) have aroused great interest amongst the scientific community [15,16].…”

“…Using an ultrasonication bath is a well-known mixing technique used for producing polymeric matrix composites [26,27] and graphene nanosheets [28], thus the assistance of this technique could also improve the dispersion. Some authors [29] presented the same hardening tendency for Al and Ni powders, with similar size distributions, dispersed by the same technique and with volume fractions of MWCNT up to 2%.…”

“…Moreover, higher value of CNT may cause CNTs non-uniformity in CNT/Al composite, and softening due to larger clusters. e existence of carbides on interfaces of CNT/Al can cause higher strengthening [52].…”
