The Effect of TiO2 Particulate Reinforcement on the Microstructure and Mechanical Properties of Binary Nano-Composite on Low Carbon Steel

In this Research, the microstructure and mechanical properties of Zn-TiO2 nano-composite, co- deposited on low carbon steel substrate were fabricated by electrocodeposition route. The structural performance of the composite coating was evaluated by scanning electron microscope (SEM) equipped with energy dispersive spectrometer (EDS). The mechanical property was carried out using a Durascan hardness tester. The result showed that the influence of TiO2 nano particles greatly enhanced the hardness behaviour. The increase in hardness is ascribed to the uniform homogeneity and dispersion stability of particles in the aqueous solution containing the nano composite.
