Abstract
- 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-Al2O3 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/Al2O3 coating is smooth and uniform; the (200) plane of Ni/Al2O3 coating is preferentially oriented in the same direction of a magnetic field; the wear resistance of Ni/Al2O3 composite coatings increases due to the uniform distribution of Al2O3 particles; and the wear mechanism of coating belongs to adhesive wear. The optimal intensity of magnetic field for Ni/Al2O3 composite coatings to obtain a good performance is 0.1 T.
