Abstract
Electrodeposition from Cu-Cr alloy on Fe substrate has been investigated by using deep eutectic solution (DES). Deep eutectic solvent is comnibation of two micture which is choline chloride and ethylene glycerol with ratio 1:2M respectively. Nevertheless, Cu deposition is easily formed in aqueous bath but it is hard for Cr due to Cr ions easier form oxide when it contact with water. The aim of this work is to develop a stable deep eutectic solvent (DES) containing Cu (II) and Cr (III) ions. Also, the main purpose of this research is to study the coating of Cu-Cr alloy on Fe substrate. 99.5% of pure iron was used as the substrate and the substrate is polished until mirror-like surface to prevent uneven coating. The substrate is mounted by a layer of epoxy resin to prevent the coating present at the backside of substrate. Thus, the crystallographic structures, morphology, chemical composition and mechanical properties of Cu–Cr deposited films are analyzed by means of X-ray Diffraction (XRD), Scanning electron microscopy (SEM), Micro Vickers hardness tester profilometer for surface roughness. The effects of plating parameters such as plating time and current density on composition, structure and surface morphology was investigated. Moreover, electrochemical measurement was done in 3.5wt% of sodium chloride (NaCl) solution to test the corrosion behaviour of coated Fe substrate. The result shows that the best parameter of this study with highest hardness and good surface is 125mA/dm² at 15minutes. The hardness and surface roughness of the substrate is 174.3 HV and 0.65μm respectively.
