oa The Corrosion Behaviour of Objects Electroplated with Platinum

If base metals are thinly coated with platinum from an aqueous electrolyte the deposit is likely to be porous, thus enhancing the susceptibility of the substrate metal to corrosion and the surface to discolouration in certain environments. This paper considers the processes involved and shows that the application of a suitable intermediate layer can effectively prevent this, so enabling the inherent properties of platinum to be utilised for a greater number of functional and decorative applications.
