Experimental study on cavitation erosion behaviours and anti-cavitation erosion mechanisms of Inconel 600 and Inconel 625 nickel-based alloy
An ultrasonic vibration device was employed to study the cavitation erosion behaviour of Inconel 600 and Inconel 625 nickel-based superalloys. The cumulative mass loss and erosion rate curves as a function of test time were used to evaluate the cavitation erosion behaviour of the two alloys. Surface...

| description | An ultrasonic vibration device was employed to study the cavitation erosion behaviour of Inconel 600 and Inconel 625 nickel-based superalloys. The cumulative mass loss and erosion rate curves as a function of test time were used to evaluate the cavitation erosion behaviour of the two alloys. Surface morphologies and changes in the main elemental composition before and after the erosion tests were observed using a scanning electron microscope equipped with an energy-dispersive spectrometer. Surface roughness was measured using a surface roughness tester to illustrate the evolution of the erosion process. The results showed that the Inconel 625 alloy exhibited better cavitation erosion resistance than the Inconel 600 alloy. A large number of intermetallic compounds present in the original material contribute to the Inconel 625 alloy's higher microhardness and elastic modulus, endowing it with greater deformation resistance during the incubation period. The contact angle results indicate that increased surface roughness enhances surface hydrophobicity, provides sites for the formation of gas nuclei, accelerates the growth and collapse of bubbles, and aggravates surface cavitation erosion damage. |
