Description
technical field [0001] The invention relates to the field of galvanic corrosion testing devices, in particular to a galvanic corrosion testing device simulating a high-temperature flowing medium environment. Background technique [0002] Petroleum, chemical industry, nuclear power and shipbuilding and other fields widely have high-temperature flowing medium working conditions. Metal materials used in this environment are often connected together by flanges, bolts, riveting or even welding. Potential differences exist between tissues, which makes the galvanic corrosion failure problem prevalent. Galvanic corrosion, also known as contact corrosion, refers to the phenomenon that dissimilar metals contact each other in the electrolyte to accelerate the corrosion of metals with low potential. This phenomenon will be extremely significant in the environment of high temperature flowing medium. Although domestic and foreign scholars have carried out a lot of research on the galvan...
