摘要：

Zirconia (ZrO2) with the thickness of about 1.5 mu m were prepared onto mechanically polished and electrochemically prepared surfaces of 316L stainless steel by direct and pulse current electrodeposition followed by annealing. The ZrO2 coatings were nanocrystalline with a tetragonal crystallographic structure. The coatings produced by direct current showed a heterogeneous structure in "cracked-mud" appearance. Pulse current produced a more uniform and dense coating with a strong mechanical barrier property. It also revealed a passive behavior on the Tafel polarization plot. The ZrO2 coatings produced on electrochemically prepared Surfaces showed a very small passive region on Tafel polarization curves. (C) 2009 Elsevier Ltd. All rights reserved.
