核电站结构材料的锌离子注入电化学研究
Electrochemical Studies of Zinc Injection into the Structure Materials of Nuclear Power Plants
摘要
Abstract
The electrochemical and semiconductor characters of oxide films formed on 304L,316L stainless steels and alloy 600 in high temperature water with zinc addition were studied. Stress corrosion cracking and occupational radiation can be retarded effectively by zinc injection to the primary circuit of pressurized water reactor (PWR). The semiconductor characters of the materials formed by zinc injection were analyzed by Mott-Schottky curves. The surface morphology and components of the corrosion oxide layers were examined and detected by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The results reveal that the smaller crystals and the complex Zn-Cr-Ni-Fe oxide were formed by zinc addition into the high temperature water. Zinc injection is a useful method to enhance the anti-corrosion ability of materials and change the semiconductor character of oxide films formed in Fe/Ni base alloys.关键词
