To reduce the effect of solid particle erosion on the aerospace engine parts, an NiTi coating has been developed by atmospheric plasma spray technology in the current investigation. Furthermore, the dependency of the solid particle erosion property on the primary gas flow rate of plasma spray coating has also been investigated. For this purpose, plasma spray coatings of NiTi alloy have been developed at different primary gas flow rates and various physical and mechanical properties have been evaluated. A correlation between the physical and mechanical properties of the coating with the solid particle erosion wear has been performed. Various phases have been obtained from the X-ray diffraction analysis such as NiTi-B2, Ni, Ti, Ni₃Ti, Ti₂Ni, NiO, TiO and Ni₄Ti₃, which also have been confirmed by energy dispersive spectroscopy method. From the microstructural investigation, various surface and interface defects such as unmelted particle formation, pores, microcracks, splat delamination etc. have been observed at the coatings developed at low primary gas flow rate and homogeneous splats have been observed from the coatings developed at higher primary gas flow rate. The coating developed at 40 lpm primary gas flow rate revealed the optimum properties like adhesion strength, microhardness, porosity, surface roughness etc. Erosion rate of the plasma sprayed NiTi coatings has been affected significantly by the coating's physical and mechanical properties. It has been revealed from the current investigation that the coating obtained from 40 lpm primary gas flow rate has less erosion rate as compared to others. Various erosion mechanisms such as groove formation, scratches, cutting, plastic deformation etc. has been observed from the microstructural analysis of the eroded samples at 45˚ impingement angle and splat fragmentation, splat delamination form the 90˚ impingement angle.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"25 ","pages":"Article 100681"},"PeriodicalIF":7.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143183267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnesium, a lightweight metal similar to natural bone, shows no toxicity and can aid in hard tissue recovery when implanted in the human body. However, its main drawback is its fast degradation rate in medical applications. Current research aims to study the effect of fiber lasers on the surface properties, metallurgical characteristics, and corrosion behavior of AZ80 magnesium-based alloy. The XRD and hardness test findings from the laser process show that some secondary phases have dissolved in the matrix, while others remain unchanged. The microhardness result for sample 4 indicated an increase to 120 HV with a loading force of 9.8 N at a holding time of 10 s. The roughness test showed a decrease from 10±0.54 µm for the AZ80 sample to 3.27±0.45 µm for sample 5. The results of the wettability test showed that the water contact angle increased from 55.1 ± 1.5° for AZ80 to 129 ± 4.3° for sample 3. The results of the polarization test showed changes in Ecorr from -1.55 mV to -1.63 mV and a shift in Icorr from 0.26 mA/cm² to 0.16 mA/cm². Sample 3 had three times higher resistance (R2 = 1710 Ω.cm²) compared to the laser-treated samples and AZ80 (R2 = 540.1 Ω.cm²). Laser-treated samples showed lower corrosion rates than untreated samples, thanks to a more uniform melted surface layer, lower roughness, and higher water contact angle. This method could enhance the corrosion resistance of the Mg-based AZ80 alloy in biomedical applications.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"25 ","pages":"Article 100695"},"PeriodicalIF":7.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143183405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The role of Bi₂Se₃, which possesses a spin-momentum locked Dirac surface state (DSS), in the CSC and SCC processes is explored using spin-torque ferromagnetic resonance (ST-FMR) and terahertz emission methods, respectively. Distinct differences in spin Hall angles are observed in ultrathin Bi₂Se₃ films on HfO_2-x, compared to those on a typical substrate, indicating the dependence on the spin-orbit interaction. Specifically, the interaction of d-orbital of the unbound hafnium in HfO_2-x and Bi₂Se₃ enhances the spin-orbit interaction. In addition, we found that the complex interaction between the surface and bulk states affects the spin diffusion length and the spin current injection region. The influence of the surface state on the conversion processes decreases as the Bi₂Se₃ film thickness increases, resulting in differing efficiency for SCC and CSC due to the asymmetrical stack structure.

However, a significant knowledge gap remains regarding MoS₂'s interfacial adhesion, a critical aspect for advancing next-generation devices. To address this, we conducted a comprehensive study investigating the interaction forces originating from the bonding between atoms that govern the adhesion of ultra-thin 2D MoS₂. Our pioneering in situ experiments, utilizing TEM-based nanoindentation, provided precise imaging and force monitoring of MoS₂'s interaction with a diamond. We employed four MoS₂-coated AFM tips with varying radii and preparation methods, with films prepared on two Si wafers subjected to different oxidation protocols. Our findings, validated by Raman and X-ray photoelectron spectroscopy, reveal unique insights into MoS₂'s interfacial behavior. We observed a decreased structural order in MoS₂ on sharper tips, particularly those without pre-deposition oxidation. These results underscore the importance of residual stress between the MoS₂ film and substrate and the influence of curvature-induced residual stress in fostering less-ordered MoS₂ structures with heightened work of adhesion. Importantly, this is the first study to report the work of adhesion for MoS₂-diamond contact.
