合金元素对锆合金耐腐蚀性能的影响概述

Summarizing for Effect of Alloying Elements on Corrosion Resistance of Zirconium Alloy

总结了合金元素对锆合金耐蚀性的影响,发现对于Zr-Nb系合金而言,Nb的固溶度对其合金的耐蚀性起主导作用,而对于Zr-Sn系合金来讲,第二相的种类、大小和分布对于其耐蚀性影响更大。少量Cu元素的加入,对含Nb锆合金的耐蚀性有很大促进。

By summarizing the effect of alloying elements on the corrosion resistance of zirconium alloys, the solid solution of Nb plays a leading role in the corrosion resistance of Zr-Nb alloys. But for Zr-Sn alloys, the species, size and distribution of the second phase are more significant. By the way, a small amount of Cu can enhance the corrosion resistance of Zr-Nb alloys a lot.
