Formation of Dimpled Tantalum Surfaces from Electropolishing
Abstract
Electropolishing of tantalum in concentrated acids has recently been reported to result in highly ordered arrays of nanoscale dimples. In this paper we study in more detail the electrochemical conditions affecting the formation of regularly dimpled surfaces on tantalum. Solution aging and anodization potential were found to play important roles. The chronoamperometric curves at different anodization potentials give some insight into the …
