Abstract: The TA15 alloy is utilized in the manufacture of aircraft engine blades due to its excellent mechanical properties and machinability. However, it does have a risk of failure because of its poor wear performance. This article discusses the preparation of FeCoCrAl medium-entropy alloy (MEA) coatings on the surface of the TA15 alloy using laser cladding at varying power levels. A friction wear test was conducted at 300 °C, and the results indicated that the FeCoCrAl MEA coating exhibited the best wear resistance when the laser power was set at 500 W. Additionally, the impact of adding Ni at this power level was explored. The findings indicated that the wear performance of the FeCoCrNiAl high-entropy alloy (HEA) coating was even better under the same conditions. Through multiple microscopic tests, the study analyzed how different power levels and compositions affected the coating properties. It was found that higher lattice distortion, increased dislocation density, and the face-centered cubic (FCC) crystal structure are the main reasons for the superior wear performance observed in FeCoCrNiAl HEA coatings.
