High temperature high pressure acoustic emission electrochemistry simulation experiment apparatus capable of loading stress

The invention provides a high temperature high pressure acoustic emission electrochemistry simulation experiment apparatus capable of loading stress. The apparatus comprises: a pressure kettle, wherein the pressure kettle is provided with an inner cavity, and a specimen is arranged inside the inner cavity; stretching test systems installed on both ends of the specimen, wherein the tension test system stretches the specimen, tests and obtains tension and a strain signal of the specimen; a solution circulation inflation system connected with the inner cavity of the pressure kettle and provided for providing a solution required by an experiment for the pressure kettle; acoustic emission probes arranged on both ends of the specimen and provided for testing an acoustic signal of the specimen; an electrochemistry test system connected with the specimen and the pressure kettle, and provided for applying polarization current on the specimen to carry out polarization, testing and obtaining an electrochemistry signal; and a data collector for collecting the simultaneously measured strain signal, the electrochemistry signal and the acoustic emission signal. With the present invention, controllable pressurizing, controllable heating and controllable inflation can be performed, and an actual working condition of the on-site material is well simulated.
