Abstract  

To reducing surface roughness, TiO2 film with different lay numbers was coated on the TiO2 film containing SrFe12O19 powder on the surface of NiTi alloy and 316L stainless steel with sol-gel method. The surface roughness of these films were investigated by SEM and surface roughometer, and the dynamic clotting time and hemolysis rate of these different roughness micromagnetic field surfaces were tested. The results showed that the blood compatibility on the micromagnetic field surface with low roughness is better, that is, smoother micromagnetic field surface can be used to further improve the blood compatibility of the materials.

Key words:  metallic materials      surface roughness      micromagnetic field      blood compatibility      sol-gel      TiO2 film
