Description

technical field [0001] The invention belongs to the technical field of material corrosion detection, in particular to a noise acquisition system based on electrochemical noise corrosion signals. Background technique [0002] With the rapid development of economy and society today, people rely more and more on the consumption and development of energy. Fossil fuels such as oil, natural gas, and coal account for a large proportion of the world's current energy consumption. Not only the energy utilization rate of fossil energy is extremely low, but also the incomplete combustion of fuel will release a large amount of toxic and harmful gases, thereby polluting the environment, and the greenhouse gases released by it will aggravate the greenhouse effect, which will endanger the sustainable development of human beings. Nuclear energy is a strong and clean energy with extremely high energy conversion efficiency and minimal pollution during the energy conversion process. It is one ...

Problems solved by technology

At present, there are very few studies on nuclear power materials in the nuclear power environment, which is a current technical blind spot. Corrosion in high-temperature and high-pressure water environments exhibits very different characteristics from those in normal temperature and pressure, and there is no complete set of detection solutions for corrosion detection. , so it is of great practical significance to study the corrosion characteristics of nuclear materials in a nuclear environment and the online detection scheme
