THE EFFECT OF HOMOGENOUS DISTRIBUTION OF NANO-PARTICLES THROUGH ULTRASONIC CAVITATION METHOD – A REVIEW
Keywords:ultrasonic cavitation method, Aluminium metal matrix, nano-composites
In recent years, Metal Matrix Nano Composites (MMNC) research is going on, in a greater extent. MMNCs overcome many limitations compared with conventional metal matrix composites (micro inclusions) such as poor ductility, low fracture toughness and machinability. Casting as a liquid phase process, is well known for its capability to produce as cast light weight components of MMNC with good reinforcement distribution and structural integrity. However, nano sized ceramic particles present difficult problems: it is extremely difficult to disperse them uniformly in liquid metals because of their poor wettability in metal matrix and their large surface to volume ratio, which easily induces agglomeration and clustering. Transient cavitations could produce an implosive impact strong enough to break up the clustered fine particles and disperse them more uniformly in liquids. It is envisioned the strong micro scale transient cavitations, along with macroscopic streaming, might effectively disperse & distribute nanoparticles into melts and also enhance wettability, thus making the production of as-cast high performance light weight MMNC feasible in ultrasonic cavitation method.
