Abstract

The effect of boron on the corrosion resistance of AI-2.5 wt% Cu alloy has been investigated with transmission electron microscopy and particle tracking autoradiography. It is shown that when AI-2.5 wt% Cu alloys are doped with 0.002, 0.004, and 0.006 wt% B, the corrosion resistance of the alloys can be greatly increased. The mechanism for boron to increase the corrosion resistance is that boron addition eliminates the preferential precipitation of a second phase at grain boundaries of the alloys. Moreover, it is shown that the segregation of boron to grain boundaries is importantly responsible for the increase of the corrosion resistance of the alloys.
