Description
technical field [0001] The invention relates to the field of physical and chemical detection and analysis of materials, in particular to an automatic intergranular corrosion test device. Background technique [0002] With the continuous development of industrial production and science and technology, stainless steel has been widely used in petroleum, chemical, aviation, shipbuilding and other departments. The intergranular corrosion of stainless steel is an important problem in production and use. Due to the occurrence of intergranular corrosion, the strength of the material is often almost completely lost, causing losses to enterprises and national properties. Therefore, in-depth research on stainless steel intergranular corrosion and its test technology will play an important role in improving the quality of stainless steel products. [0003] However, the current intergranular corrosion test technology has been in a primitive state, and the test devices used are almost al...
