研究了表面氮化钛的腐蚀、其他相关特性和生物相容性，以检验其作为耐磨植入材料的可能性。通过气体氮化法在钛上形成由TiN和Ti 2 N组成的约2微米厚的氮化层。钛离子在SBF中的溶解量低至ICP的检出限，在1%乳酸中的溶解量与钛无显着差异。圆柱形植入物在大鼠软组织中的组织反应未见炎症，1微米的细小颗粒可诱导吞噬作用，与钛相似。股骨中的植入显示新骨与植入物直接接触而形成。所有结果表明，其润湿性、耐腐蚀性、变形链球菌粘附性和生物相容性与钛几乎相当。氮化钛的表面具有与钛相当的生物相容性，作为植入材料很有前景，例如用于需要高耐磨性的牙科植入物的基台部分。
Corrosion, other related properties and biocompatibility of surface nitrided titanium were investigated to examine its possible use as an abrasion resistant implant material. The nitrided layer about 2 microm thick composed of TiN and Ti2N was formed on titanium by a gas nitriding method. The dissolved amount of titanium ion in SBF was as low as the detection limit of ICP, and that in the 1% lactic acid showed no significant difference from titanium. The tissue reaction of the cylindrical implant in soft tissue of rats showed no inflammation, and fine particles of 1 microm induced phagocytosis, which was similar to titanium. The implantation in the femor showed the new bone formed in direct contact with implants. All the results suggested that the wettability, corrosion resistance, S. mutans adhesion and biocompatibility were nearly equivalent to those of titanium. The surface of nitrided titanium was promising, with biocompatibility comparable with titanium, as an implant material such as for an abutment part of a dental implant, which requires high abrasion resistance.
