Description

technical field [0001] The invention belongs to the technical field of simulation test devices, in particular to the field of test devices for simulating the corrosion performance of materials in deep sea environments. Background technique [0002] With the exploitation and utilization of resources by human beings, non-renewable resources on land have been basically developed, and frequent oil crises often arouse people's fear of energy crises. In addition to the development of hydropower, wind energy, solar energy, and tidal energy, the seabed is a new direction for human beings to develop new energy sources. The development of marine engineering is related to environmental protection, resource development and national sovereignty security, and it is an important support for my country to build a powerful marine country. With the rapid development of marine development and utilization, the field of marine engineering is becoming one of the hot spots of scientific research ...
