Magnetic Properties and Biocompatibility of Different Thickness (Pd/Fe) Coatings Deposited on Pure Ti Surface via Multi Arc Ion Plating.

The different thickness (Fe/Pd) coatings were prepared by vacuum ion plating technology on a pure Ti substrate. The (Fe/Pd) coatings were magnetized using an MC-4000 high-pressure magnetizing machine. Then, the effect of the (Fe/Pd) coating thickness on the magnetic properties was studied. The surface and section morphology, composition, phase structure, magnetic properties, and biocompatibility of the (Fe/Pd) coatings were studied by scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, and CCTC-1 digital flux field measurement. The results showed that the (Fe/Pd) coatings were granular, smooth, and compact, without cracks. In addition the (Fe/Pd) coatings formed an L phase with a magnetic face-centered tetragonal-ordered structure after heat treatment. With the increase in the thickness of (FePd) coatings, the content of L FePd phase increased and the remanence increased. The remanence values of the Fe/Pd, (Fe/Pd), (Fe/Pd), and (Fe/Pd) magnetic coatings were 0.83 Gs, 5.52 Gs, 7.14 Gs, and 7.94 Gs, respectively. Additionally, the (Fe/Pd) magnetic coatings showed good blood compatibility and histocompatibility.
