Effect of a Pulsed Magnetic Field on the Tribological Properties of Amorphous/Nanocrystalline Composite Coatings by Supersonic Plasma Spraying
Pulsed magnetic fields can improve ferromagnetic and paramagnetic materials by improving their stress structure, domain variation, phase structure distribution and grain size of both solid and molten metals. Therefore, according to the characteristics of a pulsed magnetic field and combined with the advantages of supersonic plasma spraying technology, Ni-based coatings were prepared by pulsed magnetic field-assisted supersonic plasma spraying under a strong magnetic field of 5T. It was found that the porosity of the coatings prepared by this technique decreased obviously, the magnetic domains appeared as sheet domains and showed sinusoidal distribution, a large number of amorphous/nanocrystalline structures appeared, improved grain orientation and the coatings had good tribological properties. This study provides a new perspective on the design of high-strength metal base coatings for various applications
