| Description |
Gold deposits were formed on AA 1100 aluminium alloy using a simple chemical pretreatment
both by direct current plating (DCP) and pulsed current deposition (PCD) methods. The surface
properties of the gold deposits such as adhesion, porosity, surface morphology and corrosion
resistance formed by both DCP and PCD methods were compared by analysing them using
adhesion and porosity tests, scanning electron microscopy (SEM) and electrochemical
impedance spectroscopy (EIS). From the analyses, it is observed that the gold film formed by
the PCD method has a better corrosion resistance, less porosity and reduced grain size
compared to that formed by the DCP method.
