Abstract
The influence of the incorporation of carbon nanotubes (CNTs) on the coating structure of aluminum alloy processed by plasma electrolytic oxidation (PEO) has been studied as a function of the current density. A series of PEO coatings was applied in a silicate-electrolyte containing CNTs at three current densities, such as 50, 100, and 150 mA/cm(2). As the current density increased, the responding voltage also increased due to a gradual increment in the amount of CNTs incorporated uniformly into the coating film. In addition, a number of CNTs were observed mainly near micro-pores formed in the coating film by plasma explosive arcs, resulting in a fairly uniform coating structure with a low density of micro-pores. This phenomenon was discussed based on the electrophoretic activity of CNTs. (C) 2011 Elsevier B.V. All rights reserved.
