“…Thus, it can be inferred that the formation of regions 1, 3, 5 and 7 is due to the tribo-oxidation reaction during the friction and wear test. The obvious increment of O content indicates that tribo-oxidation occurred during the wear test [ 26 , 27 ], while regions 2, 4, 6 and 8 are mainly composed of the original film which is in accordance with the EDS analysis result of figure 4 e .…”

In the process of electrodeposition, the magnetic field would generate the magneto hydrodynamic (MHD) effect, which affects the flow and mass transfer of hydrogen evolution. Thus, the performance of electrodeposition coatings will be affected. In this work, Ni/nano-Al 2 O 3 coatings prepared by brush plating with magnetic fields were studied. The results show that the magnetic field indeed influences the morphology, texture and wears resistance. The morphology of Ni/Al 2 O 3 coating is smooth and uniform; the (200) plane of Ni/Al 2 O 3 coating is preferentially oriented in the same direction of a magnetic field; the wear resistance of Ni/Al 2 O 3 composite coatings increases due to the uniform distribution of Al 2 O 3 particles; and the wear mechanism of coating belongs to adhesive wear. The optimal intensity of magnetic field for Ni/Al 2 O 3 composite coatings to obtain a good performance is 0.1 T.

The Concept of WC-CrC-Ni Plasma-Sprayed Coating with the Addition of YSZ Nanopowder for Cylinder Liner Applications

et al. 2023

In the article, the new concept of plasma-sprayed coatings for the cylinder liner was presented. The new type of powder containing WC-CrC-Ni with a 5 and 10 wt. % addition of nano-YSZ powder was plasma-sprayed on aluminum 2017 alloy samples. The selection of optimal plasma-spraying parameters was made taking into account the thickness, porosity, and hardness of the coatings. For the coatings obtained according to the developed parameters, the analysis of their microstructure, chemical, and phase composition was performed. At the next stage, the friction coefficient of the developed coatings was tested and compared with the properties of a classic cast-iron cylinder liner. The obtained results suggest that the developed type of coating might be used for cylinder liner applications after a deeper friction analysis.

“…In summary, magnetic fields have a good effect on the processing and forming of molten metals, especially ferromagnetic metals. Supersonic plasma spraying has always been an important means of protecting the surface of structural parts because of its high temperature and speed [16][17][18] . It has unique advantages in preparing high melting point metal coatings.…”

Magnetic field-assisted forming represents an environmentally friendly, contactless and high-efficiency technology for the development of advanced in situ manufacturing. The application of this technology provides a new concept for improving the properties of ferromagnetic wear-resistant coatings. In this study, we combine magnetic field-assisted forming with supersonic plasma spraying to prepare a Ni-based coating assisted by a transverse static magnetic field. The porosity of the magnetic field-assisted coating is below 2%, the hardness of the coating increases from 638.46 to 785.45 MPa and the tribological coefficient decreases from 0.466 to 0.422. The presence of the static magnetic field directly affects the bubble movement during the forming process of the coating, which makes the bubbles escape outward and reduces the porosity of the coating. The presence of the static magnetic field also further improves the phase structure of the coating, so that the magnetic domain distribution is uniform and the hard phase inside the coating increases. Finally, the residual stress and tribological properties of the coating are also improved.
