Abstract: Nanocomposite coatings are receiving increasing attention all over the world in the last few years Research work on the synthesis and assembly of ceramic nanoparticles nano-tubes nano-wires nanopourous solids are being currently undertaken in various laboratories all over the world The nanocomposite coatings are those in which atleast one of the constituent phases has at least one dimension less than 100 nm in size The promise of nanocomposites lies in their multifunctionality the possibility of realizing unique combinations of properties unachievable with traditional materials The challenges in obtaining this sophisticated goal are tremendous That includes control over the distribution in size dispersion of the nano-size constituents tailoring and understanding the role of interfaces between structurally and/or chemically dissimilar phases and their effect on bulk properties However incorporating nanoparticles into a coating matrix are to overcome the difficulty of dispersing large volume fractions of nanoparticles into the suitable matrix without sacrificing the mechanical properties of the resulting composite The use of nanoparticle in the matrix system has become a subject of interest in engineering applications due to potential changes in physical properties of nanocomposites These changes in properties come from two aspects of nanoparticles increased surface area and quantum effects associated with nanodimentional particles structure These factors can change or enhanced properties such as reactivity strength magnetic and dielectric properties etc of nanocomposites Out of various composite/ nanocomposite coating technologies electroless coating technology is one of the best technology that withstands with recent development in the nanoscience and technology to provide coatings for various applications For last five years several researchers have proposed various schemes to controlled various parameters like pH temperature and concentration of second phase particles etc For electroless Ni-P based composite coatings successfully and are able to co-deposit second phase nano particles in the electroless Ni-P matrix that led this classical electroless coating technology to a further step that is electroless nanocomposite coatings It has been recently reported that the electroless micro/nanocomposite coatings can be carried out by two ways [34] depending upon the compatibility of reactions and also the process parameters of electroless bath namely (i) conventional composite coating ie co-deposition of nano particles (ii) non-conventional coating ie in-situ preparation of nanometer vi size particles within the electroless bath There are number of combinations…
