High-temperature erosion wear testing device

The utility model relates to a high-temperature erosion wear testing device, belonging to the technical field of material wear, erosion and protection. The testing device mainly comprises a control cabinet, a heating power supply and a water cooling system which are connected with an erosion tank body. Sand grains are conveyed to a rotating sand slinging disc by a feeder, and are slung under the action of the centrifugal force and impact the surface of specimens. The specimens are used for heating by utilizing the self-generated resistance heat, and the high-temperature and erosion wear resistance performance of the coating can be evaluated through computing the mass difference before and after the specimens wear. In the utility model, a plurality of specimens can be placed in the single test, so that the testing efficiency is improved, the sand feeding quantity can be controlled accurately, and the testing temperature, the erosion speed and the erosion angle of the erosion wear can be randomly changed in tes
