AN EXTENSIVE REVIEW ON THE ROLE OF METAL MATRIX NANOCOMPOSITES IN THE RECENT RESEARCH AREAS

Metal matrix nanocomposites have received more focus in the last two decades because of their desirable alternative features. Many researchers have made several attempts to identify the suitable nanoreinforcement particles for getting improved results in various applications. Many of them tried to improve the properties of several metal matrix nanocomposite materials including mechanical properties, electrical properties, barrier properties, structural properties, moisture permeability, etc., with the help of a variety of techniques. Research study results revealed that the addition of nanosized reinforcement particles improved the mechanical and wear characteristics of aluminum-based metal matrix composites. Metal matrix nanocomposites are being employed in many application areas such as in biomedical field, self-cleaning marble coating application, antimicrobial application and wear-resistant coating application. This review workhas gone through a bulk of research works related to metal matrix nanocomposites. The entire study has been grouped under a few major categories such as synthesis of nanocomposites, characterization study on various nanocomposites, application areas of various nanocomposites, optimization works carried out on nanocomposites, and risk management of nanocomposites.
