Abstract
The Nickel- Fly Ash (Ni-FA) coating are electrodeposited on aluminium alloy 7075 (AA7075) via various sodium citrate composition at different heat treatment process. The aim of this study is to examine the mechanical properties which are hardness and corrosion properties of Ni-FA composite coating AA7075 based on the various composition of sodium citrate. Other than that, to examine the effect annealing process to the properties of Ni-FA composite coating The electrodeposition process using a citrate bath that contain sodium citrate at 400C temperature. Various sodium citrate which are 30 g/L, 50 g/L, 70 g/L and 90 g/L and heat treatment process at 200 oC and 400 oC. The surface morphology of coating was examined by using Scanning Electron Microscopy (SEM), the characterization by X-Ray Diffraction (XRD) and the compositional analysis by X-Ray Fluorescence (XRF). The morphologies and structure of Ni-FA coating become more compact and denser when undergo heat treatment process at 200 0C and mechanical properties was decreased by increasing the sodium citrate composition.
