Abstract

We have established the micro-magnetic field on the surfaces of 316L stainless steel and NiTi alloy through the magnetization process of sol–gel prepared TiO₂ thin film with the powder of SrFe₁₂O₁₉. The nano-sized with brown color of SrFe₁₂O₁₉ powder was verified by transmission electron microscope. By using X-ray diffraction, surface roughometer, and corrosion experimental test, the deposited thin film can decrease the etching of body fluid as well as prevent the hazardous Ni ions released from the metal. Moreover, with evaluation of dynamic cruor time test and blood platelets adhesion test, we found the micro-magnetic field of the thin film can improve the blood compatibility.
