本文研究了一种新型的原子氢渗透速率测量传感器在含有不同种类和浓度缓蚀剂的盐酸溶液中的信号水平(渗氢电流);同时,采用慢应变速率拉伸试验(SSRT)和断口的扫描电镜(SEM)分析以及金相观察,研究确定了两种锅炉/管道用钢及其带焊缝材料在上述酸液中的强度/脆性,并以此对传感器的信号输出水平进行标定。借助于两者之间的对应关系,赋予传感器的测量信号以特定的物理意义。经过这样标定以后的电流值,即可作为评价锅炉钢在
In this paper, we study the signal level (hydrogen permeation current) of a new kind of hydrogen permeation rate measuring sensor in hydrochloric acid solution containing different kinds and concentrations of corrosion inhibitor. At the same time, using the slow strain rate tensile test (SSRT) Scanning electron microscopy (SEM) analysis and metallographic observation were performed to determine the strength / friability of the two boiler / pipe steels and their weld materials in the acid solution and to calibrate the signal output level of the sensor. With the correspondence between the two, the measurement signal given to the sensor has a specific physical meaning. After this calibration after the current value, you can evaluate the boiler steel in
