This facility is used to solve the corrosion and aging failure problems of engineering material and components under the atmospheric environment in the fields of industrial and city infrastructure. Large scale simulation testing facilities were constructed to study the effects of atmospheric environment on engineering materials and failure regularity.

Aims

1.Integrated corrosion chamber simulates the corrosion problems of metallic and inorganic non-metallic structural materials caused by urban atmosphere, industrial atmosphere and marine atmosphere in the central and eastern regions of China. The simulated environmental factors include temperature, humidity, light, rainfall, salt spray, atmospheric pollutants and alternation of dry and wet.

2.Western environment area simulates the special corrosion and aging problems of polymer and passive metal structural materials in the western plateau and desert region of China. The simulated environmental factors include high and low temperature alternation, humidity and strong ultraviolet radiation.
