Abstract: The effect of sustainable degradable eco-friendly extract juice on the precipitation and re-enforcement of Zn-SnO₂ alloy matrix with the aim of producing an eco-friendly composite material for engineering structural applications was investigated. Composite samples were produced from these mixtures and the effect of coconut juice (5-15% concentration) on the microstructure evolution, the mechanical properties of the composites and electrochemical behaviour were investigated. Scanning electron microscope (SEM-EDS) and atomic force microscope (AFM) were used to study the surface morphology and the surface adherent properties of the coatings. Micro-hardness behaviours were investigated by means of high impact diamond Dura scan microhardness tester. The result shows that Zn-SnO₂-15CJ sulphate co-deposition contributed to increase hardness than Zn-SnO₂ alloy. It was observed that Zn-Zn-SnO₂-15CJ sulphate has excellent corrosion progression at ambient temperature. The hardness performance shows that developed Zn-SnO₂-15CJ is increased by 80% compared to as received sample and 25% compared to Zn-SnO₂.

Keywords: sustainable extract; composite; re-enforcement; X-ray diffraction spectrometer; XRD; microstructure.
