Due to the ever-changing shape and temperature of the erosion fluid, it is difficult for the general erosion test equipment to have the universality of the erosion test.

Therefore, it is necessary to invent an erosion device that can more realistically simulate various extreme working conditions involved in materials in actual industrial production, so as to realize the laboratory simulation of complex service environments and the effective evaluation of the performance of service materials. For this type of service The design, development and reliability evaluation of materials in the environment are of great significance. At present, most of the research on such test devices under various extreme working conditions is in the exploratory stage or the function is relatively single, and it is impossible to realize the coupling verification of multiple working conditions.
