摘要	Cr(III) conversion layers were synthesized on the nanocrystalline zinc with two grain sizes, 22 nm and 40 nm. Their corrosion behaviors were examined by potentiodynamic polarization and electrochemical impedance spectroscopy. The results shows that a more uniform and none-micro-crack conversion layer is formed on sample with grain size 22 nm compared with that formed on the sample with grain size 40 nm. Refining the grain size can markedly enhance the corrosion resistance of trivalent chromium conversion layer. (C) 2009 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
