Abstract
The paper reviews the preparation of the different metallic nanocomposites. In the preparation of composites, especially in the case of nanocomposites, interfacial phenomena play an important role. This review summarizes the literature on various interfacial phenomena, such as wettability and reactivity in the case of casting techniques and colloidal behavior in the case of electrochemical and electroless methods. The main contribution of this work lies in the evaluation of collected interfacial phenomena and difficulties in the production of metal matrix composites, for both nano-sized and micro-sized reinforcements. This study can guide the composite maker in choosing the best criteria for producing metal matrix composites, which means a real interface with good adhesion between the matrix and the reinforcement. This criterion results in desirable mechanical and physical properties and homogenous dispersion of the reinforcement in the matrix.
Highlights
Metal matrix composites are made up of a metal matrix and a reinforcing substance, which may be metal or another substance
It was found that the proportion of Al2 O3 in the coating decreased significantly with increasing CTAB concentration. They conclude by stating that the stability of the sol formed by the bath and Al2 O3 is due to the fact that CTAB changes the zeta potential of the particle to a positive value
In the casting method and powder metallurgy, it is a well-known fact that the surface of the matrix is covered by an oxide layer
Summary
Metal matrix composites are made up of a metal matrix and a reinforcing substance, which may be metal or another substance. According to the preparation method [26,27], we can group composites into stir casting [28,29,30,31,32], assisted stir casting [33], pressure infiltration [34,35,36,37], pressureless infiltration [38], laser melting [39], electrochemical [40], electroless deposition [41,42,43] and powder metallurgy [44,45,46,47,48,49,50] methods.
