Test device for simulating splash zone

The invention relates to the technical field of corrosion and protection of materials and particularly relates to a test device for simulating a splash zone. The test device includes a box body which is provided with a solution circulating system. A splash generating device, which is wrapped by a water-absorbing material wrapping layer, is disposed in the middle of the box body. A corrosion sample rack, a ventilating device, a temperature detecting and controlling element are disposed around the splash generating device. The splash generating device is respectively connected to the solution circulating system and a power device which is connected to a controlling system in which program controlling is contained. By means of the test device, a splash solution particle can be generated and a splash environment can be simulated. Splash efficiency, splash speed and splash form can be accurately controlled so that an excellent correspondence is achieved between a simulation result of a corrosion experiment and a site corrosion result in the splash zone is achieved, thereby increasing experimental efficiency, saving labor intensity and resources and reducing an experimental cost. Meanwhile, experimental data is convenient to be collected so that integrity of the experimental data and reliability of the experimental result are ensured.
