High-entropy alloys (HEAs) are promising coating materials for wear resistance applications. However, the preparation of HEA coatings with powder has the disadvantages of high cost and low efficiency. In this study, an innovative triple-wire plasma arc cladding (TW-PAC) method was used to prepare HEA coatings. Nonequiatomic Cr-Fe-Ni-Ti x (x is Ti wire feeding speed, x = 0, 0.5, 0.8 and 1.0 m/min, denoted as Ti 0 , Ti 0.5 , Ti 0.8 and Ti 1.0) HEA coatings were successfully prepared by using three commercial wires (ERTi-2, ER304L and Cr 20 Ni 80 wire). With increasing Ti content, the structure of the Cr-Fe-Ni-Ti x HEA coatings changed from the single FCC phase to the FCC + γ′ (Ni 3 Ti) + Laves (Fe 2 Ti) phase, and the microhardness of the coatings increased from 137 HV to 873 HV. Due to the addition of Ti, Ni 3 Ti and Fe 2 Ti phases with high hardness precipitated in the alloy coating, accompanied by the solid solution strengthening effect of the FCC phase, the wear resistance of the coatings was significantly improved (from 9.67 × 10−4 to 1.49 × 10−4 mm3/N·m). The results of this study contribute to the preparation of thick HEA coatings overlarge areas at low cost and with high efficiency and provide new insights into Cr-Fe-Ni-Ti x HEA coatings. • Triple-wire plasma arc cladding (TW-PAC) of Cr-Fe-Ni-Tix high-entropy alloy coatings. • High-entropy alloy coatings were prepared using three commercial wires. • The phase of the coatings changed from FCC to FCC + Ni 3 Ti + Fe 2 Ti with the addition of Ti. • The wear resistance of the coatings was significantly improved with addition of Ti.
