摘要：

We investigated the corrosion behavior of commercially pure (CP) Ti with both ultrafine-grained (UFG) and coarse-grained (CG) microstructures. It was found that the UFG Ti is more resistant to corrosion than its CG counterpart. The superior corrosion resistance of UFG Ti is believed to result from rapid passivation of UFG Ti and the impurity segregation to grain boundaries in CG Ti. (C) 2004 Acta Materialia Inc.
