| 摘 要： | 采用微弧氧化技术, 以NaAlO2和Na5P3O10为电解液体系, 在镍铬合金表面制备微弧氧化陶瓷膜, 研究镍铬合金表面形成的微弧氧化陶瓷膜对镍离子析出的影响. 用扫描电子显微镜(SEM)及X射线衍射(XRD)对膜层进行表征, 用等离子体发射光谱仪及电化学方法检测成膜前后镍铬合金中镍离子在人工唾液中的析出量及合金的耐腐蚀性能. 实验结果表明, 镍铬合金表面形成的主晶相为γ-Al2O3的微弧氧化陶瓷膜可有效阻止镍离子析出, 提高了镍铬合金的耐腐蚀性能.

| Abstract: | The effect of microarc oxidation ceramic membrane on NiCr alloy on the release of Ni ions by means of microarc oxidation was studied with NaAlO2 and Na5P3O10 as electrolytes.The membrane was characterized by means of scanning electron microscopy(SEM) and X-ray diffraction(XRD).The corrosion resistance and the release of Ni ions from NiCr alloy were analyzed by electrochemical test and ICP-OES.The results indicate that the major crystalline phase on NiCr alloy is γ-Al2O3,which can prevent Ni ions from release and improve the corrosion resistance of NiCr alloy. |

| Keywords: | NiCr alloy microarc oxidation ceramic coating Ni ion release corrosion resistance |
