Testing device and method for synergistic effect of ultrahigh-temperature wet oxygen atmosphere and load

The invention discloses an ultrahigh temperature wet oxygen atmosphere and load synergistic effect test device and method.The device comprises a front cavity and a rear cavity, the front cavity comprises a front main cavity body, a C-shaped notch and an air outlet pipeline, and the rear cavity comprises a rear main cavity body, a U-shaped notch, an air inlet pipeline, a temperature collecting hole and a diverter. And the universality is very high. According to the device and the method, the defect of incomprehensiveness of research on a single factor of high-temperature wet oxygen atmosphere or load of a material is overcome, the wet oxygen atmosphere is uniformly dispersed in the high-temperature-resistant impurity-free cavity and is in full contact with the gauge length section of the sample to realize an ultrahigh-temperature wet oxygen oxidation environment, and a mechanical testing machine is matched; the method can be used for researching the influence of the synergistic effect of the load and the ultra
