Beschreibung
Zusammenfassung:	The invention discloses a high-entropy alloy/ceramic composite coating and a preparation method thereof. The coating is formed by spraying high-entropy alloy/ceramic composite powder; the high-entropy alloy/ceramic composite powder is prepared from the following components in percentage by mass: 10 to 25 percent of high-entropy alloy CoCrNiAlTiNb, 20 to 35 percent of Cr2C3 and 40 to 70 percent of WC; according to the high-entropy alloy CoCrNiAlTiNb, the atomic ratio of Co to Cr to Ni to Al to Ti to Nb is (20-45): (10-25): (10-25): (5-10): (5-10): (1-5). The composite coating provided by the invention has the advantages of low porosity, strong binding force, cavitation erosion resistance, wear resistance, corrosion resistance and the like, and has unique advantages in the aspect of solving cavitation erosion and wear of hydraulic equipment. 本发明公开了一种高熵合金/陶瓷复合涂层及其制备方法。所述涂层由高熵合金/陶瓷复合粉末通过喷涂而成；所述高熵合金/陶瓷复合粉末按照质量百分比，由10～25％的高熵合金CoCrNiAlTiNb、20～35％的Cr2C3和40～70％的WC组成；所述高熵合金CoCrNiAlTiNb按照原子比，Co：Cr：Ni：Al：Ti：Nb＝20-45：10～2
