人工唾液中修复材料电偶序测定及腐蚀倾向的研究

通过对口腔修复材料稳态电位测量，获得修复材料在口腔唾液中电偶序，即电位正端至电位负端顺序是Ｔｉ－７５合金，ＴＡ２型纯钛，Ｃｏ－Ｃｒ合金，１８：８不锈钢，Ｎｉ－Ｃｒ合金，Ｇｒ２型钛钛修复体。测定稳态电位，可提示在选择口腔修复材料时，应用耐腐蚀性能好的材料；为防止电偶腐蚀，应尽可能选择同种材料，或者选择电偶序中稳态电位相近的金属、合金做修复材料。

Determination on the Electric Mate Order of Prosthodontic Materials in Artificial Saliva

Electric mate corrosion of the different prosthodontic materials has been noticed in oral cavity. The aim of this investigation was to determine corrosion potential of prosthodontic materials, and to acquire the electric mate order in artificial saliva. That will conduct us to select the materials of resistance corrosion. For resistance electric mate corrosion, it's better to use same materials, or to use close materials of the electric mate order.
