Abstract

The invention relates to a high-temperature lasting test device and method for environment corrosion. The test device comprises a quartz sealing system arranged in a high-temperature lasting test machine, and a gas distribution system which is communicated with the quartz sealing system and can provide corrosive gas or water vapor. The quartz sealing system comprises a quartz tube used for carrying a metal sample, an upper end flange used for sealing the upper end of the quartz tube is arranged at the upper end of the quartz tube, a lower end flange used for sealing the lower end of the quartz tube is arranged at the lower end of the quartz tube, the upper end flange is provided with gas outlet holes communicated with the quartz tube, and the lower end flange is provided with corrosive gas inlet holes and water vapor inlet holes, wherein the corrosive gas inlet holes and the water vapor inlet holes are communicated with the quartz tube. The high-temperature lasting test device and method for environment corrosion are especially suitable for testing the high-temperature lasting performance of metal materials in harsh serving environments, the problem that in the prior art, tests can only be carried out under high-temperature dry air is solved, the device can carry out high-temperature lasting tests for special environment atmospheres, and the lasting performance in certain special atmospheres such as smoke and water vapor can be truly reflected.

Description

technical field [0001] The invention relates to the field of high-temperature endurance tests for metal materials, in particular to a high-temperature endurance test device and method for environmental corrosion. Background technique [0002] An important purpose of the high-temperature endurance test is to determine the maximum stress value that does not cause fracture within a specified duration when the material is subjected to a constant load at a certain temperature, that is, the high-temperature endurance strength. In addition, mechanical performance parameters such as elongation after fracture, reduction of area and notch sensitivity coefficient of the material can also be obtained. Through the high-temperature endurance test, it is possible to study the fracture law, mechanism and influencing factors of materials under the action of external load (external force) or the combined action of load and environmental factors (temperature, medium and loading rate, etc.). I...
