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
This study examines the passive film properties of Sn-5Sb alloy processed through Equal Channel Angular Pressing (ECAP) for application in gas turbine bearing pads. The alloy was analyzed in a 0.2 M Na 2 B 4 O 7 solution utilizing multiple electrochemical methods, including cyclic voltammetry (CV), potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS). The microstructure and corrosion products were analyzed utilizing optical microscopy (OM), X-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM). The findings indicated that ECAP processing enhanced the grain structure, leading to a protective layer with improved corrosion resistance. Positron Annihilation Lifetime Spectroscopy (PALS) and Coincidence Doppler Broadening Spectroscopy (CDBS) were utilized to identify corrosion-induced damage.
