Summary: Ni-P-Al2O3-PTFE nanocomposite coatings were prepared by jet electrodeposition to enhance the wear resistance and toughness of mechanical parts. A new method of unidirectional deposition was proposed and the effect of current density on the surface quality and mechanical properties of the coatings was studied. The results showed that the unidirectional deposition process improved the coating quality and adjusting the current density to the midpoint value resulted in coatings with the best surface morphology and lowest wear and friction properties, indicating excellent wear resistance and toughness.

Summary: Ni-P-Al2O3-PTFE nanocomposite coatings were prepared by jet electrodeposition to enhance surface protection and strengthening. The influence of current density on the properties of the coating was studied. Analysis of the microstructure, surface morphology, and element content showed that an optimal current density of 10 A/dm(2) resulted in a composite coating with excellent surface morphology, high content of Al and F elements, and improved deposition rate. The coating exhibited exceptional wear resistance and toughness, making it suitable for various applications. This research provides theoretical and technical support for the development of high-performance multi-component nanocomposite coatings through jet electrodeposition.

Summary: In order to achieve high hardness and excellent toughness in tool coatings, (AlCrSiN/TiN)20/Ti multilayer multiscale bionic (MB) coatings were prepared on WC-6 wt% Co substrates with a TiAlN buffer layer by adjusting the negative bias voltage of the Ti layer. The nanocomposite structure of nanocrystalline AlN, CrN, TiN, and amorphous Si-N(O) in the nano multilayer of AlCrSiN/TiN provided excellent hardness, as confirmed by TEM, XPS, and XRD analyses. The multilayer structure and the Ti layer enhanced the crack resistance and adjusted the toughness, with the MB4 coating sample exhibiting the best performance in terms of H/E*, H3/E*2, and scratch crack propagation resistance (CPRs). These results can contribute to the application of coated cutting tools in high-speed cutting processes.

Summary: This study investigated the mechanical and tribological properties of niobium-alumina composites obtained by spark plasma sintering. The addition of niobium improved fracture toughness and wear resistance, leading to higher wear resistance against steel counterbody. Furthermore, alumina exhibited higher wear rate when sliding against Al2O3 counterbody at higher loads. Wear regime maps allowed the visualization of improved wear resistance of niobium-alumina composites.

Summary: An efficient Al2O3-based nanocomposite coating was developed for the top thermally insulative layer of thermal barrier coatings (TBCs), showing higher scratch coefficient and decent scratch resistance compared to monolithic Al2O3. However, the addition of carbon nanotubes (CNT) in the nanocomposite coatings did not significantly improve the scratch toughness. On the other hand, the mere addition of 8YSZ and 3YSZ in the Al2O3 matrix showed an increment in scratch toughness compared to that of monolithic Al2O3 coating.

Summary: This paper proposes an automated Ejection Fraction estimation system from 2D echocardiography images using deep semantic segmentation neural networks. Two parallel pipelines of deep semantic segmentation neural network models have been proposed for efficient left ventricle segmentation, and three different neural networks, UNet, ResUNet, and Deep ResUNet, have been implemented. The most accurate model achieved high Dice scores for left ventricle segmentation in both systolic and diastolic states. The proposed system can remove the eyeball estimation practice and reduce inter-observer variability.
