Abstract

The invention relates to a test equipment, specially relates to a high temperature corrosion test system of material under the much stress state. The test system is composed of loading system, sealing system, heating and temperature controlling system, corrosion aura hybrid system and support platform frame; the invention partly solves the problem of mechanics and chemical action unable to combined in the existing test technology, it provides a high temperature corrosion test system of materials under the much stress state with simple operate, uniform test temperature, high test precision, low cost.

Description

technical field [0001] The invention relates to a test device, in particular to a high-temperature corrosion test system device for materials under multiple stress states. Background technique [0002] With the development of energy, power, petrochemical and other industries and the continuous progress of modern science and technology, the production process is developing towards high temperature, high pressure and large scale. All these make the problem of high temperature corrosion of engineering materials more prominent. The high temperature corrosion of metal not only causes the corrosion of metal, but also destroys the excellent performance of metal. Corrosion in the form of high temperature oxidation, carburizing, sulfidation, nitriding, etc. are familiar to people. For some rare high-temperature corrosion forms, such as metal dusting (Metal Dusting MD), although a lot of work has been carried out, its specific mechanism and protection work have not been fully unders...
