[ 1 ] - An Investigation on the Electrodeposition Mechanism of Ni-TiO2 Nanocomposite Coatings
In this research, a sol-modified composite electrodeposition technique that combines the sol-gel method with the conventional electrodeposition process was utilized to deposit Ni-TiO2 nanocomposite coatings. Cyclic voltammetry and chronoamperometry techniques were applied to study the influence of the TiO2 sol concentration on the deposits’ electrochemical behavior. The results clearly showed t...
[ 2 ] - A Study of Zeta Potential of Plasma Sprayed Hydroxyapatite Coating in Four Simulated Physiological Solutions
The zeta potential magnitude and the duration of its changes have been thought to be directly related to the surface reactivity, the governing of osteoconductivity and availability of valuable information in determining the anticipated in-vivo performance of implants. In this study the zeta potential of plasma sprayed hydroxyapatite (HA) was evaluated in various simulated physiological solution...
[ 3 ] - Synergistic Influence of Benzoate Ions on Inhibition of Corrosion of Mild Steel in 0.5m Sulfuric Acid by Benzotriazole
The influence of benzoate anions on the corrosion inhibition effect of benzotriazole (BTA) for mild steel in sulfuric acid has been investigated. The investigation was carried out by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. The addition of benzoate ions greatly enhances the inhibition efficiency of BTA in a synergistic manner. This effect has bee...
[ 4 ] - Interface Characterization of Plasma Sprayed Hydroxyapatite Coat on Ti 6Al 4V
Hydroxyapatite (HA), a material proven to be biocompatible within the human body, has been produced to a high level of purity. This material has been applied as a coating on Ti-6Al-4V alloy by using the air plasma spraying technique. The coat was characterizted with SEM, XRD, FTIR and Raman spectroscopy methods to consist of a mixture of calcium phosphates including HA mainly and traces of tric...
