Electrodeposition of Nickel and Titanium Dioxide from Electrolytic Glycine Bath

Abstract

This research aims to study theelectrodeposition of nickel-titania coatings from glycine bath. Ni–TiO2 coatings with varying Titania content were electrodeposited on copper substrate employing glycine electrolyte. The different conditions which affect the deposition process such as current, plating time, concentration of nickel and glycine, PH and temperature were investigated. The Titania content in the coatings increased with increasing Titania content in the bath and decreased at high current density, the effect of pH shows an increase in Titania up to pH 8, Enhancement of thickness of the coating show whenever increase of the percentage of contents of the electrolyte bath, time and temperature. The obtained coatings were characterized using x-ray fluorescence (XRF) and Atomic absorption Spectroscopy (A.A.S).The optimum conditions of this bath were found as follow: PH 8, current 0.4 A/cm􀬶.The percentage, of the incorporated TiO2was 2.7695%.
