| Abstract Scope |
Magnetic field-assisted electrosynthesis presents new opportunities for microstructure control and enhanced processing efficiency. In particular, a superimposed magnetic field during electrodeposition induces a magnetohydrodynamic (MHD) effect that is generated by the Lorentz force which may enhance convective flow and has been shown to incorporate particles in excess of conventional electrodeposition. Here, Ni/Al<sub>2</sub>O<sub>3</sub> is co-deposited with permanent Ne<sub>2</sub>Fe<sub>14</sub>B magnets in a modified Watt’s type bath. We explore different processing parameters, such as magnetic field orientation and Al<sub>2</sub>O<sub>3</sub> particle size, and their influence on the coating structure. Small-scale wear characterization is examined in light of the microstructural modifications. |
