Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In this work, the mechanical mixing process was successfully used to inoculate FeCrNiMnAl powder with CeO 2 nanoparticles, which contributed to the heterogeneous nucleation of fine equiaxed grains. In this way, the nano-CeO 2 /FeCrNiMnAl HEA composite coating with low dilution, cracks-free was successfully fabricated. The effects of different addition of nano-CeO 2 (0 wt%, 0.5 wt%, 1.0 wt%, 1.5 wt%, 2.0 wt%) on the microstructure and properties of HEA composite coatings were mainly explored. The thermodynamic calculations on HEA composite coatings with different contents of CeO 2 were conducted to predicted their phase composition. With the modification of nano-CeO 2, the microstructure exhibited homogenous, fine-grained and equiaxed. To further reveal the effect of CeO 2 on the microstructure, this work studied the columnar-to-equiaxed transition (CET) behavior of HEA coating during solidification process. As a comparison, the heterogeneous nucleation behavior of fine equiaxed grains induced by nano-CeO 2 in HEA composite coatings was studies. The results showed that CeO 2 nanoparticles were enriched at the grain boundaries of HEA composite coating, and it not only had a drag effect, but also hindered the growth and development of grains. However, excessive nano-CeO 2 (2.0 wt% CeO 2 ) could affect the forming quality of HEA coating and have a negative impact on the mechanical properties. After regulating the grain structure, the mechanical properties of HEA composite coating have been greatly improved. While 1.0 wt% nano-CeO 2 was added, the microhardness of HEA composite coating reached to the maximum (670.4 HV 0.2 ). Compared with substrate, the average microhardness has increased almost 91.5 %. The friction performance of 1.0 wt% CeO 2 /FeCrNiMnAl HEA composite coating was the optimal as well and the wear rate reached 3.12 × 10 −6 mm 3 /N m. The tribo-oxide layer was produced on the worn surface of HEA composite coating.
