Problems solved by technology

[0004] It is more objective and realistic to study the immersion, erosion and corrosion behavior of different materials and explore the aging failure mechanism of materials in the real sea environment. However, due to the complex and changeable factors affecting the real sea environment, it is often difficult to carry out relevant experimental research in this case for a long time. Continuously, at the same time, due to the harsh environment of the actual sea, it is not conducive to the in-depth development of related scientific research activities, and a set of wave erosion aging test equipment that simulates the actual sea environment is developed, and the wave erosion state of the ship at different speeds is simulated in the laboratory. It is helpful to carry out long-term, continuous and in-depth research on sea erosion aging tests, which will provide objective data for the design and maintenance of production equipment used in actual sea environments, and further improve Provide scientific basis for improving material performance and improving material quality
