The primary focus of the study is to explore the influence of annealing on the various properties like phase formation,microstructure evolution and wear analysis of equiatomic AlCoCrFeNiTi high entropy alloy (HEA) coatings developed byatmospheric plasma spray technique. Post deposition, annealing was performed at three different temperatures of 700 °C,900 °C and 1200 °C, respectively, for a time period of 180 min. X-ray diffraction (XRD) studies revealed that AlCoCrFeNiTiHEA coating comprises two BCC solid solution phases. The deposited samples were characterized using scanning electronmicroscopy (FESEM), surface profilometer, chemical analysis using x-ray photoelectron spectroscopy (XPS) and Fouriertransform infra-red spectroscopy (FTIR). The dilution level study revealed the strong metallurgical bonding between coatingand substrate. Microhardness of the AlCrCoFeNiTi was found to be marginally decreased by increasing the annealingtemperature due to coarsening of grains and the deposited coating microhardness was found to be 768.48 ± 16 HV0.2. Weartest analysis performed using the ball-on disc test revealed that, there is a significant decrease in wear resistance after heattreatment at 1200 °C. Beyond 900 °C, annealing decreased the microhardness and wear resistance due to coarsening ofgrains. The wear volume rate of the unannealed as-deposited coating was found to be 2.8 × 10–7 mm3N−1 m−1 and the coatingannealed at 700 °C, 900 °C, and 1200 °C had a wear volume rate of about 2.89 × 10–7 mm3 N−1 m−1, 2.87 × 10–7 mm3 N−1 m−1,7.29 × 10–7 mm3 N−1 m−1, respectively.
