摘要：
The TiVZrCrAl high entropy alloy (HEA) coatings with different deposition temperatures were prepared on Zr-4 alloys by using radio frequency magnetron sputtering (RFMS) technology. The effect of the deposition temperature on the microstructure and mechanical performance of the coatings was studied. In addition, the corrosion properties of the coating deposited at 300 degrees C were tested in static pure water at 320 degrees C and 11.3 MPa for 45 days. The mechanism for the corrosion progress of the TiVZrCrAl HEA coating was assessed in detail. The result shows that AlVO4 formation is beneficial to prevent the dissolution of Al in the form of AlOOH, and finally enhance the anti-corrosion properties of the Zr-4 substrate.
