The present study investigated the effects of ultrasound frequency on the microstructure, mechanical properties, and wear characteristics of nickel-based chromium carbide coatings. The results demonstrated that the phase composition of nickel-based chromium carbide coatings prepared by laser cladding after ultrasonic treatment remained unchanged. Ultrasonic interference disrupted the Marangoni flow, leading to cavitation degassing and a subsequent decrease in porosity. The dilution rate increased from 11.2% to 16.3%, with surface flatness and defect suppression attaining optimal levels at 34 and 36<!-- --> <!-- -->kHz, respectively. Microscopically, at frequencies of 26 and 28<!-- --> <!-- -->kHz, columnar grains were refined to 13~15μm; at 32 and 34<!-- --> <!-- -->kHz, cavitation and acoustic flow synergized to form equiaxed grains of 3~5μm at the top; at 36<!-- --> <!-- -->kHz, the cavitation bubble radius and dendrite spacing were optimally matched, with columnar crystals refined to 3.5μm and equiaxed crystals reaching 2.1μm, accounting for 65% of the total. The high-frequency attenuation effect intensifies at frequencies above 38<!-- --> <!-- -->kHz, leading to a decline in refinement efficiency. The average microhardness of the coating increases with increasing ultrasonic frequency, from 597.9 HV_0.5 to 738.1 HV_0.5.

The grinding marks transformed deep and wide plow grooves to shallow and narrow plow marks, with the depth exhibiting a decrease from 99.3μm to 95.4μm and the width demonstrating a reduction from 1570.2μm to 1466.3μm. The phenomena of pile-up and peeling were almost eliminated. Ultrasonic processing achieves a transition from severe plastic deformation to mild plowing through a three-in-one mechanism of \"carbide refinement-interface metallurgical transformation-matrix strengthening,\" which significantly enhances the wear resistance and stability of the coating. Furthermore, ultrasonic vibration has been demonstrated to effectively reduce the formation of cracks in the cladding layer, enhancing its quality and extending the service life of components.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"26 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144521468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When SFO was deposited preferentially, the ferromagnetism and EB effect of the SFO/LMO bilayer were relatively weak. Conversely, when LMO was deposited preferentially, the large tensile–strain provided by the SrTiO₃ (STO) substrate led to an increased presence of Mn⁴⁺ ions within the LMO layer in the LMO/SFO bilayer, in which the double exchange mechanism of the Mn³⁺–O–Mn⁴⁺ ions not only resulted in robust ferromagnetism but also coupled with SFO to generate a significant EB effect.

The hollow architecture of CoP substantially increases the exposure of active sites and promotes proton diffusion dynamics, that favor proton reduction for enhancing photocatalytic hydrogen evolution.

However, substantial volume expansion (~300%) during charge/discharge cycles leads to structural degradation and detachment from the current collector, resulting in rapid capacity fading. To address these challenges, we synthesized silicon anodes with a dual-layer carbon coating comprising hard carbon and soft carbon, using sucrose and pitch as precursors. We also investigated the impact of a caramelization process on carbon layer formation. The dual-layer carbon coating prevents direct contact between silicon and the electrolyte, reducing continuous electrolyte decomposition. It combines the excellent mechanical strength of hard carbon with the flexibility and superior electrical conductivity of soft carbon, effectively mitigating silicon’s volume expansion during cycling and enhancing its electrical conductivity. This synergy improves both the physical and electrochemical performance of the anodes. Various physical analyses (FE-SEM, TGA, BET/BJH, RAMAN) and electrochemical analyses (GCD, EIS, CV) validated these findings. Notably, the Si@pit/suc_cm sample with dual-layer carbon coating exhibited a 4.01% improvement in initial Coulombic efficiency at a 0.1 C-rate and a 27.38% enhancement in cycle life at a 1 C-rate over 100 cycles compared to bare Si.
