We have already started to witness the power of nanotechnology. Ever wondered how is your phone water resistant? Or how could a Ferrari reach 340km/h? Thanks to the power of nanotechnology! Let us have a sneak peak on how the nano crystalline structures are formed.
The secret sauce of this immense power of nano materials lies in the process of grain size reduction. The material reaches its meta stable state wherein the proportion of atoms at the grain boundaries is equivalent or higher than the proportion of atoms inside the grains. This can be achieved by using electrodeposition process. The materials which we get after this process have advanced properties and are commonly called as nano crystalline materials.
Due to the process of grain size reduction, dislocations are reduced and hence they attain superior properties compared to polycrystalline or microcrystalline materials. Nano materials have:
✓ Increased Strength
✓Enhanced Diffusivity
✓ Improved Ductility
✓ Reduced Density
✓ Reduced Elastic Modulus
✓ Higher Electrical Resistivity
✓ Corrosion and Wear Resistance
✓ Lower Thermal Conductivity
✓ Enhanced Magnetic Properties
Electrodeposition plays a very important role in nanotechnology. The field of nano materials is fascinating and has attracted a lot of researchers. There has been an impeccable advancement in this field, yet there is a lot to be explored.
