Abstract

Tribological properties of AlCoCrCuFeNi high-entropy alloy were studied after annealing at various temperatures. X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, microhardness tester and pin-on-disc tribometer analyses were performed to reveal the microstructure, composition, microhardness and tribological behavior variations. With the heat treatment temperature increasing, time taken for friction coefficient going through the rapidly dropping down and then into the stable period increases, the white sheets structures and their size in dendrite area of the AlCoCrCuFeNi alloy becomes bigger, however BCC content declined dramatically. Then, the average friction coefficient of the AlCoCrCuFeNi/Si₃N₄ sliding friction pair increase from 0.037 to 0.115, and the pin wear loss increase from 3 to 11 µm.
