Doctoral
This work focuses on the mechanism of silver dissolution for biomedical and hygienic coating applications. The research work began from the investigation of silver dissolution behaviour from pure silver and silver-platinum alloys in solutions with or without chloride using the technique of cyclic volammetry (CV). A zero resistance amperometry (ZRA) measurement was carried out to study the effect of platinum on the silver dissolution behaviour in 0.89%wt. NaCI solution. The mechanism of silver dissolution from pure silver and silver-platinum alloys in 0.89%wt. NaCI solution was proposed by an equivalent circuit model under the investigation of electrochemical impedance spectroscopy (EIS). It …
