Material Performance Testing System for High-Temperature Water-Oxygen Corrosion Environments

Abstract

The present invention belongs to the technical field of material property testing under special environments, and in particular relates to a material property testing system for a high-temperature water-oxygen corrosion environment, comprising a mechanical property testing system, an environmental simulation system, a heating system, and a data acquisition and control system; the mechanical property testing system comprises a support frame, a semi-enclosed simulation cabin arranged on the support frame, a loading mechanism, a fixture for clamping a specimen, and a deformation measuring element for measuring the deformation amount of the specimen; the environmental simulation system comprises a premixing and preheating chamber, a plurality of gas flow controllers connected to the premixing and preheating chamber, a water vapor generator, and a gas composition sensor for detecting the gas composition in the premixing and preheating chamber; the outlet of the premixing and preheating chamber is connected to the inlet of the semi-enclosed simulation cabin through a pipeline; the heating system comprises an induction heating system, and a heating end thereof extends into the semi-enclosed simulation cabin or is arranged around the semi-enclosed simulation cabin.
