Abstract: Two different laboratory carbonyl nickel sample types were electrochemically dissolved under anodic conditions to study the effects of dissolution on different decomposition temperatures and gas pressures used during the growth of the samples. Electrochemical and microscopy techniques were used to monitor the change in surface chemistry and morphology over the course of the 120 minute dissolution. Scanning Electron Microscopy (SEM) and White Light Interference Microscopy (WLIM) were used to determine the differences in the initial structure and dissolution characteristics of the different decomposition temperatures. Analysis of the surface showed that the boundary areas between the different decomposition conditions were most affected by the dissolution. Surface roughness calculations also concluded that during the dissolution, the surface of each sample became much rougher and open pit dissolution was the primary mechanism of dissolution after 120 minutes of dissolution had elapsed.
