英文摘要	Titanium and zirconia are bioinert materials lacking bioactivity. in this work, surface modification of the two typical biomaterials is conducted by mg-ion-implantation using a mevva ion source in an attempt to increase their bioactivity. mg ions were implanted into zirconia and titanium with fluences ranging from 1 x 10(17) to 3 x 10(17) ions/cm(2) at 40 kev. the mg-implanted samples, as well as control (unimplanted) samples, were immersed in sbf for 7 days and then removed to identify the presence of calcium and phosphate (ca-p) coatings and to characterize their morphology and structure by sem, xrd, and ft-ir. sem observations confirm that globular aggregates are formed on the surfaces of the mg-implanted zirconia and titanium while no precipitates are observed on the control samples. xrd and ft-ir analyses reveal that the deposits are carbonated hydroxyapatite (hap). our experimental results demonstrate that mg-implantation improves the bioactivity of zirconia and titanium. further, it is found that the degree of bioactivity is adjustable by the ion dose. mechanisms are proposed to interpret the improvement of bioactivity as a result of mg implantation and the difference in bioactivity between zirconia and titanium.
