In this study, an Fe₇₈Si₉B₁₃ amorphous coating (Fe^AC) was fabricated on ZK60A alloy via high-velocity oxygen fuel (HVOF) spraying to regulate degradation kinetics while enhancing bioactivity. The Fe^AC exhibited a dense and homogeneous architecture with a thickness of approximately 170.03 μm, an ultralow porosity of 0.95%, and a high amorphous phase fraction of 76.19%. The surface hardness reached 808 HV_0.2, nearly an order of magnitude higher than that of the ZK60A substrate. Electrochemical and immersion tests demonstrated that the coating dramatically reduced the degradation rate to 0.024 mm/year, which is 116.6 times lower than that of the ZK60A substrate (2.798 mm/year). This significant improvement is attributed to a dual-passivation mechanism. On the one hand, a dense Fe₂O₃/SiO₂ enriched layer formed on the coating surface effectively suppressed chloride ion attack and charge transfer. On the other hand, the Si⁴⁺ and B³⁺ ions released during coating degradation promoted the formation of a secondary protective film. More importantly, the Si-OH and Fe-OH functional groups on the Fe^AC surface chemically anchored Ca²⁺ and PO₄³⁻ ions, thereby inducing the formation of a hydroxyapatite layer (Ca/P = 1.65) within 9 days, indicating strong potential for osteogenesis. Collectively, these findings demonstrated that the Fe^AC synergistically enhanced corrosion resistance and bioactivity, providing a highly promising surface modification strategy for Mg-based orthopedic implants.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":679,"journal":{"name":"Journal of Thermal Spray Technology","volume":"35 5","pages":"1961 - 1978"},"PeriodicalIF":3.4,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148314675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this limitation, we propose a low-temperature plasma nitriding strategy that provides synergistic strengthening by delivering a nitrided surface layer while its inherent holding stage naturally yields an annealing effect. The effects of this process on the fracture toughness, corrosion, and wear resistance of as-sprayed AlCoCrFeNi_2.1 coatings were studied. The results demonstrate that the as-sprayed AlCoCrFeNi_2.1 coatings form a 2.62 ± 0.25 μm AlN/CrN composite layer after low-temperature plasma nitriding, while the concomitant thermal energy heals pores and microcracks. Compared to the non-nitrided coatings, the nitrided coating exhibits a 57% increase in surface hardness coupled with improved fracture toughness and interlayer bonding. Notably, the corrosion resistance and wear resistance of as-sprayed coatings are significantly enhanced after the plasma nitriding treatment, which is attributed to the dual effects of nitride formation and defect healing.

The microstructure of the iron matrix within the composite coatings predominantly features planar crystals, cellular crystals, columnar crystals, columnar dendrites, and epitaxial crystals.

Previous studies have largely focused on static CMAS testing, which does not fully replicate real engine conditions. To better simulate real-world scenarios, a commercially available CMAS (AFRL-03) powder was deposited by an atmospheric plasma spraying (APS) process onto 8YSZ coatings. The effects of different spray angles (90°, 60°, and 30°) of the CMAS powder on various TBC surfaces, i.e., as-sprayed, laser-glazed, and polished, were systematically evaluated. SEM/EDS analyses were used to characterize the morphology and elemental composition of the resulting CMAS deposits. Results showed that the polished and laser-glazed surfaces exhibited comparable CMAS weight gain, whereas the as-sprayed coatings accumulated the lowest amount. With respect to spray angles, a 30° impact angle produced the least CMAS deposition compared with 90° and 60°. Furthermore, neither surface temperature (525-1100 °C) nor coating porosity (10-25%) significantly affected CMAS infiltration, likely due to the short impingement duration and relatively low surface temperatures. However, at high temperatures ~ 1500 °C, CMAS infiltration into the pores and cracks of the 8YSZ coatings became evident. In addition, smoother surfaces promoted the formation of more uniform, spherical splats, while rougher surfaces tended to produce shattered or fragmented deposits.</p></div>","PeriodicalId":679,"journal":{"name":"Journal of Thermal Spray Technology","volume":"35 5","pages":"1786 - 1799"},"PeriodicalIF":3.4,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148314764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The WC content in the coatings was designed to be 35, 40, 45, 50 and 55%, respectively. The microstructure and phase composition of the coatings were analyzed by scanning electron microscope, energy-dispersive spectrometer and x-ray diffractometer.

While TiO₂-Fe₃O₄-graphene composites have been widely reported in powder suspension systems, their direct consolidation into functional coatings via AD has not previously been achieved due to challenges associated with heterogeneous particle size, density mismatch, and differential impact behavior. In this work, composite powders comprising nanoscale Fe₃O₄, micrometer-scale TiO₂, and layered rGO were synthesized and deposited without post-annealing or binders. Systematic optimization of deposition parameters (2 Torr chamber pressure, single pass, 10 SLM gas flow, and 4 mm/s substrate translation speed) enabled stable impact consolidation of this multi-component system into coatings approximately 5-7 μm thick, as confirmed by surface profilometry and cross-sectional analysis. Phase integrity was preserved after deposition, demonstrating that AD can be extended beyond single-oxide systems to complex ternary photocatalysts. Compared to aerosol-deposited pure TiO₂ coatings fabricated under comparable conditions, the ternary composite exhibited significantly enhanced methylene blue degradation under both UV and natural sunlight irradiation. Normalized photocatalytic efficiency per unit mass was consistently higher for the composite, reflecting synergistic interactions among TiO₂ (photoactive phase), Fe₃O₄ (redox mediator and charge-transfer facilitator), and rGO (electron-transport network and visible-light sensitizer). Electrochemical impedance spectroscopy further revealed reduced charge-transfer resistance in the composite coating, directly correlating improved electrical conductivity with photocatalytic performance. These results establish aerosol deposition as a viable room-temperature route for immobilizing complex multi-component photocatalysts into dense functional coatings, overcoming limitations associated with powder-based systems. The demonstrated feasibility of ternary composite consolidation significantly broadens the application scope of AD for advanced environmental remediation coatings.</p></div>","PeriodicalId":679,"journal":{"name":"Journal of Thermal Spray Technology","volume":"35 5","pages":"1927 - 1948"},"PeriodicalIF":3.4,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148314763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X-ray phase analysis revealed the predominant presence of the WC phase without signs of W₂C formation, which is attributed to the low thermal impact during the detonation spraying process. The introduction of chromium into the binder phase contributed to a more uniform distribution of carbide particles and enhanced the adhesion strength of the coating to the substrate. Electrochemical tests demonstrated that the WC-Co-Cr coating exhibits higher corrosion resistance compared to WC-Co due to the formation of Cr-containing passive films.

In an oil environment, the coefficient of friction of all samples decreased to 0.09–0.12, which is associated with the formation of a lubricating film.
