Abstract
Recent advancements in the field of coating have shown that the Ni-Al2O3 electrodeposited coatings are of excellent wear-resistant, corrosion-resistant. In this study, Ni-Al2O3 composite coating is produced by electrodeposition process by using standard watts bath due to the advantage over other coating techniques. Al2O3 nanoparticles are co-deposited on AA6061 with Nickel. There are many parameters that influence the coating characteristics, however, in this study temperature, current density and percentage of nanoparticle loading are considered as significant parameters. Optimization of the coating parameters is examined by using the Taguchi method. The coating morphology and microstructure are studied using Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD). The dry sliding wear behaviour of composite coatings is tested on a pin-on-disc wear test rig.
