Physicochemical and Mechanical Performance of Freestanding Boron-Doped Diamond Nanosheets Coated with C:H:N:O Plasma Polymer

Materials (2020)

Michał Rycewicz Łukasz Macewicz Jiří Kratochvíl Alicja Stanisławska Mateusz Ficek

The physicochemical and mechanical properties of thin and freestanding heavy boron-doped diamond (BDD) nanosheets coated with a thin C:H:N:O plasma polymer were studied. First, diamond nanosheets were grown and doped with boron on a Ta substrate using the microwave plasma-enhanced chemical vapor deposition technique (MPECVD). Next, the BDD/Ta samples were covered with nylon 6.6 to improve their stability in harsh environments and flexibility during elastic deformations. Plasma polymer films with a thickness of the 500-1000 nm were obtained by magnetron sputtering of a bulk target of nylon 6.6. Hydrophilic nitrogen-rich C:H:N:O was prepared by the sputtering of nylon 6.6. C:H:N:O as a film with high surface energy improves adhesion in ambient conditions. The nylon-diamond interface was perfectly formed, and hence, the adhesion behavior could be attributed to the dissipation of viscoelastic energy originating from irreversible energy loss in soft polymer structure. Diamond surface heterogeneities have been shown to pin the contact edge, indicating that the retraction process causes instantaneous fluctuations on the surface in specified microscale regions. The observed Raman bands at 390, 275, and 220 cm-1 were weak; therefore, the obtained films exhibited a low level of nylon 6 polymerization and short-distance arrangement, indicating crystal symmetry and interchain interactions. The mechanical properties of the nylon-on-diamond were determined by a nanoindentation test in multiload mode. Increasing the maximum load during the nanoindentation test resulted in a decreased hardness of the fabricated structure. The integration of freestanding diamond nanosheets will make it possible to design flexible chemical multielectrode sensors.

On the Durability of the Hydraulic Satellite Motor Working Mechanism in Overload Condition

Advances in Materials Science (2016)

Marek Szkodo Alicja Stanisławska Paweł Śliwiński

Abstract The paper presents the newest construction of the hydraulic satellite pump/motor. In this study, the fracture of the hydraulic satellite motor working mechanism is investigated. Factors influencing the durability of satellite working mechanism have been described. The durability of the hydraulic satellite motor working mechanism at a load, corresponding to a pressure of 15 MPa supplied with refined rapeseed oil is very low. Analyses of construction and laboratory tests showed that the satellites teeth wear out the fastest. Results showed that bending fatigue and surface contact fatigue of the satellites are the main cause of the hydraulic satellite motor working mechanism failures.

Thermal affection on hydrogen diffusion in different structures of nickel alloy

Multidiscipline Modeling in Materials and Structures (2025)

Pasquale Cavaliere Behzad Sadeghi Zhenghan Chen Alicja Stanisławska

Purpose Based on previous research, we choose nickel alloy 718 as the research material and use finite element analysis (FEA) to simulate the hydrogen diffusion in lattice, grain, boundary grain and dislocation in different thermal loads, aiming to understand the intricate mechanisms underlying hydrogen diffusion in nickel-based alloys, which will contribute to driving progress in the field of hydrogen diffusion for understanding and management HE. Design/methodology/approach In this research, we focus on nickel alloy 718, creating a numerical model with traps to simulate the hydrogen diffusion in lattice, grain, boundary grain and dislocation with different thermal loads, by FEA. Findings The results demonstrated that traps improve the hydrogen saturation in materials, and because of thermal saturation and heat flux, higher temperatures decrease the hydrogen solubility and increase hydrogen diffusion velocity, which can decrease hydrogen saturation. Originality/value Based on our previous research and publications, we developed a finite element model to define the hydrogen trapping in different microstructural features of nickel-based superalloys. The model is very complex with a very large number of elements capable of obtaining very affordable results.

The effect of dehydration/rehydration of bacterial nanocellulose on its tensile strength and physicochemical properties

Carbohydrate Polymers (2020)

Alicja Stanisławska Hanna Staroszczyk Marek Szkodo

Bacterial nanocellulose (BNC) is a natural biomaterial with a wide range of biomedical applications. BNC contains 99 % of water which makes it too thick to be used as a bioimplant material. The aim of the work was to determine the effect of the BNC dehydration followed by rehydration on its mechanical and physicochemical properties, in the context of the use of BNC as bio-prostheses in the cardiovascular system. Dehydration involved the convection-drying at 25 and 105 °C, and the freeze-drying, while rehydration - the soaking in water. All modified BNC samples had reduced thickness, and results obtained from FT-IR, XRD, and SEM analysis revealed that 25 °C BNC convection-dried after soaking in water was characterized by the highest: tensile strength (17.4 MPa), thermal stability (253 °C), dry mass content (4.34 %) and Iα/Iβ ratio (1.10). Therefore, 25 °C convection-dried BNC followed by soaking in water can be considered as a material suitable for cardiovascular implants.
