| Abstract: | The corrosion behaviors of as-cast ZA27 alloys in neutral 3% NaCl solution have ben studied. The results of corrosion tests of salt spray test and immersion test in 3%NaCl solution showed that alloying elements and heat treatment have effect on corrosion characteristics.The corrosion characteristics of ZA27 alloys are both intergranular and selective corrosion. The selective corrosion shows a characteristic of lots of white rusts on the surfaces of specimens. The intergranular corrosion has the characteristic of corrosive cracks along grain boundaries obviously. |
