Metric Options: Counts1 Year3 YearSelecting 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
NiCrAlY coatings without and with a Cr or Mo diffusion barrier were fabricated on Ti-42Al-5Mn alloys by vacuum plasma spray. The microstructure evolution and inter-diffusion behavior were studied via isothermal oxidation tests conducted at 950 °C. The results revealed that substantial inter-diffusion happened in the coating without a diffusion barrier, accelerating the degradation of NiCrAlY coating. While the addition of Cr or Mo diffusion barrier deferred the inter-diffusion phenomenon, and Mo performed much better than Cr due to its high stability. The thickness of the inter-diffusion zone with the Mo diffusion barrier was just about one-fifth of that for NiCrAlY coating after 200 h oxidation. The results could provide comprehensive understanding of the microstructural evolution of NiCrAlY coating, which was essential for controlling the inter-diffusion behavior and improving the durability of NiCrAlY coating.
