The invention discloses an erosion-corrosion experiment device for simulating a spray splashing area. The experiment device is supported by a base and comprises a lifting system, a sample clamping system, a power system, an injection system, an ultraviolet illumination aging system, an electrochemical testing system and a temperature control system, wherein a hydraulic lifting frame is fixedly arranged on the base and is controlled to ascend or descend by a pedal or a pressure relief knob; the sample clamping system and the power system are mounted on the hydraulic lifting frame; a medium groove is formed in one side of the hydraulic lifting frame; the sample clamping system is arranged inside the medium groove; the upper part of the medium groove is sleeved by a sealing cover, and the sealing cover and the medium groove are sealed through a rubber sealing ring. According to the erosion-corrosion experiment device, the influence on a material erosion-corrosion behavior caused by factors such as wave impact strength, impact period, sand content, oxygen content, temperature and illumination can be researched, the failure process of an ocean spray splashing area structure is accurately simulated, and the defects of a conventional material erosion-corrosion research device for simulating a splashing area are overcome.
