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%.
