| Abstract Scope |
Solid particle erosion describes a wear phenomenon, where a high-pressure gas stream carrying solid particles with kinetic energy impacts the component surface. Eutectic high-entropy alloys (EHEAs) show an excellent strength-ductility combination and good work hardening behavior, which are feasible for erosion application. In this study, an improved air-jet sandblaster was used to test the erosion performance of EHEAs. Instead of building a hole on the sample surface, several shallow channels were formed to ensure the consistency of the abrasive flow rate and to collect a bigger dataset for analysis. A non-contact optical profilometer was used to calculate the erosion rate. The effect of particle speed and impact angles (20, 30, 45, 60, and 90 degrees) on EHEAs were investigated. The results show that compared a 316 stainless steel, EHEA has low erosion rates, and it shows an obvious superiority in a high-speed particle condition. |
