The system can couple multiple factors such as high and low temperature, humidity, salt spray, ultraviolet light, and periodic infiltration, and is suitable for the test evaluation of metal materials, composite materials, coating materials, and small structures under laboratory simulated corrosion media. Background technology:

[0002] With the rapid development of the shipping industry, the activity areas and navigation environments of ocean-going vessels such as LNG carriers, crude oil tankers, large cargo ships, and polar ships not only involve typical environments such as temperate, subtropical, and tropical zones, but have also gradually expanded to global ocean environments with extreme low-temperature environments such as high-latitude cold zones and polar regions, and even cross-domain extreme ocean environments from tropical to polar regions. The leap in the navigation capabilities of ocean-going vessels has placed higher demands on the performance of materials. How to truly and fully simulate the global navigation environment of ships and achieve efficient and accurate testing and evaluation of material properties is the key to improving material performance. Based on this, the construction of an accurate and realistic comprehensive test system simulating marine environments to quickly evaluate the performance of materials in full-sea and cross-sea environments is of great significance to the design, material selection, and micro-arcing inspection of ocean-going ships and extreme environment engineering structures.

[0003] At present, common accelerated corrosion test equipment for materials in marine atmospheric environments include salt spray test chambers, gas corrosion test chambers, UV aging test chambers, constant temperature and humidity test chambers, high and low temperature alternating (wet heat) test chambers, and periodic immersion corrosion test chambers. Although these equipments have high precision and accurate control, their functions or environments are relatively simple and cannot meet the test and evaluation needs of accelerated material corrosion in complex environments.
