Prior electrodeposition of nanocrystalline Ni-Ce O2 film

Abstract

With the prior electrodeposition of nanocrystalline Ni film without or with the dispersions of Ce O2 nanoparticles, a carbon steel was chromized using a conventional pack-cementation method but at a greatly decreased temperature (700°C). The chromized coating on the Ni-Ce O2 film had a considerable thickness, throughout which chromium was continuously distributed, and an extremely low scaling rate during oxidation at 700°C in air. The study offers a novel approach for fabricating a low-temperature chromized coating with a desired oxidation performance on conventional steels. © 2006 The Electrochemical Society.
