    Abstract

    In recent years, there has been increased interest in the research and development of metal matrix composite coatings (MMCs) due to their expected engineering applications. These composite coatings can impart functional properties such as wear, corrosion and oxidation resistance, dispersion hardening or self-lubrication relative to pure metal. As a result of which, MMCs can protect the metal substrates more effectively against severe environments during operation and also they can impart some functional properties. Zinc aluminate (ZnAl2O4), a member of spinel family offers many advantages such as high thermal and chemical stability, hydrophobic behavior, high mechanical resistance, low sintering temperature and high quantum yield and it is used as transparent conductor, dielectric material and optical material. The tribological property of the ZnAl2O4 nanoparticles as an additive in lubricant oil has been recently evaluated with four-ball test and thrust-ring test. However, there are no reports on the synthesis and properties of electrodeposited Ni-ZnAl2O4 coatings. ZnAl2O4 particles were synthesized by solution combustion method.
