Zusammenfassung:	The invention relates to a corrosion-resistant material as well as a preparation method and application thereof. The preparation method of the corrosion-resistant material comprises the following steps: in a protective gas atmosphere, spraying NbMoTaW-based refractory high-entropy alloy powder on the surface of a base material by adopting plasma spraying to prepare a coating; the temperature of the base material is 180-200 DEG C; the spraying distance of the plasma spraying ranges from 80 mm to 100 mm, the spraying voltage ranges from 78 V to 80 V, and the spraying current ranges from 500 A to 550 A. Under the spraying parameters, the flying speed and temperature distribution of the high-entropy alloy particles are uniform, the temperature of the flying particles is high, and sufficient melting of the high-entropy alloy powder is guaranteed. In the spraying process, the temperature and the flying speed of flying particles are high, it is guaranteed that the particles collide with the surface of a base materia
