Effect of Fe Content on Corrosion Resistance of High Aluminum Bronze
The effects of Fe content on corrosion resistance of new high aluminum bronze were studied by using alloying method, EPMA, SEM and static immersing corrosion test. The results show that, with the increase of Fe content, K phase forms, which is mainly composed of AlFe, AlFe3 and so on, and is dispersed in the alloy, resulting in the refinement of microstructure and the increase of corrosion resistance of the alloy. When Fe content is 5wt%, the corrosion resistance of the alloy is best, but when Fe content is over 5wt%, the corrosion resistance of the alloy decreases.
