Electro-chemical corrosion simulator with in-situ loading

Abstract

The invention provides an electro-chemical corrosion simulator with in-situ loading and relates to the technical field of materials. The simulator consists of an electrolytic bath, an electrolytic bath upper cover, a reference electrode, an auxiliary electrode, a working electrode, a tensile testing machine fixture, a temperature gauge and an electrolyte, wherein the tensile testing machine fixture is connected with a tensile testing machine, the working electrode passes through a lower hole for mounting a sample along the electrolytic bath and is hermetically fixed; the electrolyte is filled in the electrolytic bath; an upper hole, used for mounting the sample, in the electrolytic bath upper cover and the lower hole, used for mounting the sample, in the electrolytic bath are kept in a same longitudinal plane; the reference electrode, the auxiliary electrode and the temperature gauge are respectively in a small hole, used for inserting the reference electrode, of the electrolytic bath upper cover, a small hole, used for inserting the auxiliary electrode, of the electrolytic bath upper cover and a small hole, used for inserting the temperature gauge, of the electrolytic bath upper cover. During operation, load is applied, and an electro-chemical corrosion simulation test with in-situ loading is performed. The device can be used for not only regulating the parameters such as temperature, pH value and ionic species of the electrolyte, but also regulating the load size and the load mode in real time.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to an in-situ loaded electrochemical corrosion simulation device. Background technique [0002] With the development of society and the deterioration of the natural environment, severe climate anomalies often occur, and extreme weather occurs frequently. Such as sandstorms, freezing disasters, etc., the structure in service is forced to bear a certain load, resulting in a decline in the mechanical properties of the components, and at the same time the surface properties of the material are seriously affected. Therefore, the reliability of the material in the natural environment is also increasingly severe. challenge. [0003] The reliability of materials is an important index to measure the service life of materials. The condition of a material surface is directly related to its later service life. For materials, especially the reliability of metal materials in the natural ...
