A CoCrFeNiMo high-entropy alloy (HEA) coating was prepared on Ti6Al4V alloy by plasma spraying technique. The microstructure and phases of the obtained coating were analysed using an ultra-depth-of-field microscope and X-ray diffraction, respectively. The electrochemical corrosion properties of CoCrFeNiMo HEA coating in 3.5% NaCl, 0.1 M H 2 SO 4  and 0.1 M NaOH solutions were comparatively evaluated using an electrochemical workstation, and the corrosion mechanisms were also discussed by the corrosion models. The results show that the CoCrFeNiMo HEA coating is mainly a solid solution structure of face-centered cubic, which forms mechanical bonding at the coating interface. The charge transfer resistance  Rct  of 597 × 10 16  μA·cm –2  in 0.1 M H 2 SO 4  solution is the highest and the corrosion current density  icorr  of 4.203 × 10 –7  μA·cm –2  also presents the lowest among the three kinds of corrosive solutions, which shows the highest electrochemical corrosion resistance. As a result, the sequence of corrosion resistance is in 0.1 M H 2 SO 4  solution &gt; in 3.5% NaCl solution &gt; in 0.1 M NaOH solution, in which the corrosion resistance is further improved by the passive film on the CoCrFeNiMo HEA coating.
