Multi-factor comprehensive marine environment simulation corrosion test device and method

Abstract

The invention, which belongs to the technical field of corrosion test devices, particularly relates to a multi-factor comprehensive marine environment simulation corrosion test device and method. Thedevice comprises a machine body (1), a test box body (6), a water delivery mechanism (9) and an environment conversion mechanism (12). A camera (10) and a temperature and humidity sensor (11) are respectively arranged on the inner wall of the upper space of the machine body (1); the test box body (6) can contain seawater; a plurality of sample racks (7) for clamping and fixing a sample substrate (8) are arranged in the test box body; and a water delivery mechanism (9) is communicated with the test box body (6) in the upper-layer space of the machine body (1) through a pipeline and delivers seawater into the test box body (6). The device can be switched at will to simulate various complex marine environments, seawater in use can be recycled and screened, the cleanliness of the seawater is guaranteed, and the accuracy of a marine environment simulation corrosion test is improved.

Description

technical field [0001] The invention belongs to the technical field of corrosion test devices, and in particular relates to a multi-factor comprehensive marine environment simulation corrosion test device and method. Background technique [0002] The marine corrosion environment is extremely harsh. If effective protection measures are not taken for metal structures in the marine environment such as ships, cross-sea bridges, offshore oil platforms, ocean-going ships, and seawater cooling systems of nuclear power plants, they will be damaged due to corrosion in just a few years. . The marine corrosion environment is very complex, and the corrosion of materials in the marine environment is affected by various environmental factors such as temperature, humidity, radiation, salt spray deposition, and alternating wet and dry conditions. Therefore, it is of great significance to carry out corrosion test research on materials in marine environment. At present, there are mainly two...

Problems solved by technology

The former method can truly reflect the corrosion resistance of the material in the actual ocean, and the data is accurate and reliable, but the test conditions cannot be controlled, the test period is long, the speed is slow, and it consumes a lot of manpower and material resources

The conditions of the latter method are controllable, the test period is short, and t
