The invention discloses an electrochemical test device for microbial corrosion under the action of stress coupling. The device includes an electrochemical workstation, a bending loading fixture, a corrosion reaction pool and a constant temperature box; the corrosion reaction pool is in the shape of a "concave" shape, and the end face of the inverted "concave" shape opening has a hole, and a gasket is installed at the opening. The middle opening of the sheet; the bending loading fixture is fixed on the upper end face of the opening; the bending loading fixture includes a loading bracket, a loading rod and a loading module which is located inside the loading bracket and can move up and down; at least a pair of rollers are fixed on the inner side of the upper foot of the loading bracket , the upper end face of the loading module is provided with one or more grooves and rollers that can be accommodated in the grooves. The test device of the present invention can ensure the accuracy of the test data, and has the advantages of convenient disassembly, simple design and small volume. |
