新锆合金水侧腐蚀性能研究

Study on Water-side Corrosion of New Zirconium-based Alloys

摘要: 通过对国产新锆合金N18、N36的堆外腐蚀性能考验,获得了新锆合金的腐蚀和吸氢数据,并与Zr-4合金的数据进行了比较。实验结果表明:与Zr-4相比,N18、N36的抗腐蚀性能得到了明显的提高。

Abstract: The out-of-pile corrosion tests were carried out for new zirconium-based alloys N18 and N36. The thickness of oxide film in the surface of specimen was measured by the methods of optical microscopy and eddy current. And the hydrogen absorptions and hydride were also got. The studies indicate that N18 and N36 have a super corrosion resistance than Zr-4.
