Abstract
Abstract The corrosion behaviour of bronze alloy prepared by equal channel angular pressing (ECAP) was investigated in 3.5 wt. % NaCl solution. Immersion corrosion tests and different electrochemical techniques were carried out. The results showed that {ECAPed} bronze samples exhibited higher corrosion resistance compared with the as-cast alloy and the passive current density decreased with increasing number of passes. Moreover, the morphology of alloys indicated that the corrosion damage on the surface of {ECAPed} bronze was smooth and uniform while the as-cast alloy suffered from selective corrosion.
