Influence of Anodic Polarizations on the Electrodeposition of Metals on BDD films

摘要

The deposition of Pt and Cu is attained in polycrystalline, boron doped diamond films which are submitted to pre anodizations made in O{sub}2 evolution potentials. Such pre-treatments increase the relative surface area of the metallic deposit. As a tentative explanation for this effect, a model based on steric hindrance caused by O-terminations of the step represented by surface diffusion of metal nuclei is presented.
