探讨和解决了电化学噪声技术在核电环境材料腐蚀损伤检测应用的关键问题，建立了基于零阻电流（ZRA）检测的SCC电化学噪声测试体系。采用小面积的Pt或表面热喷涂陶瓷涂层的工作电极材料作为对电极，研制适用于核电现场检测的多种电化学传感器。运用Compact RIO模块化仪器和设计制作的基于ZRA电路的电化学噪声测试模块，实现电位-电流噪声的同步测量和采集。成功研制出便携式核电材料损伤检测系统。应用研制的测试系统和电化学传感器研究了高温高压和动态水环境304不锈钢的电化学噪声谱特征。并初步实现了在役核电站辅助车间不锈钢管道表面直接腐蚀检测和钢厂动力锅炉连续排污管的现场腐蚀检测，取得了比较满意的结果。
- Abstract:

Key problems of electrochemical noise techniques used in corrosion detecting and monitoring of nuclear power materials were discussed and resolved, and then the electrochemical noise test system was established based on zero resistance ammeter (ZRA) mode. Several electrochemical sensors for nuclear power field detecting were developed by using Pt of small area or working electrode with thermal spraying ceramic coating as counter electrode. Combined with Compact RIO modular instrument, the designed electrochemical noise test block could measure and acquire the current and potential noise simultaneously....
