Implementing hydrogen oxidation reaction on Pt for controlling counter electrode processes
Published 2025-06-01“…This increases the level of control required over the experimental system for proper materials evaluation. The choice of counter electrode material become crucial, as Pt dissolution at high voltages may cause contamination to the working electrode, especially when studying reductive processes in reactions such as oxygen reduction reaction (ORR), H2 evolution reaction (HER), and the CO2 reduction reaction. …”

Sand Erosion Wear Analysis of 300M Steel Sand Based on Johnson-Cook Model
Published 2025-06-01“…Exposed components such as aircraft landing gear sleeves are prone to erosion wear from hard sand and gravel particles due to prolonged exposure to high fluid velocities and particle-concentrated environments.In order to explore the influence of this process on 300M steel,the actual working conditions were simulated by pneumatic sandblasting equipment, and the finite element simulation model of the multi-particle erosion target material based on the Johnson-Cook damage evolution model was established by ABAQUS/Explicit.In addition, the morphological characteristics of 300M steel were observed using X-ray diffractometer and laser confocal microscope.The erosion and wear amounts of sand and gravel under different environmental factors were analyzed through the combination of experiments and simulations, and an erosion rate model suitable for 300M steel was proposed to achieve quantitative analysis of the counter-erosion and wear process.Results showed that compared to fine sand particles (20 mesh), coarse sand particles (60 mesh) increased the average surface roughness by 14.29%and enlarged the average maximum erosion pit size by 23.08%.With the increase of the erosion angle and erosion speed, the surface roughness of 20 mesh and 60 mesh sand grains exhibited a trend of first increasing and then decreasing, and the maximum surface roughness was achieved at 30°,which correlated with morphological fluctuations.When the erosion angle was fixed at 30°, with the increase of erosion pressure (0.3~0.5 MPa), the overall increase ranges of erosion wear caused by 20 mesh and 60 mesh sand particles were 6%~8%and 4%~5%, respectively.…”
