评估了Ti-15Mo合金在含有0.01、0.03、0.06和0.5 M NaF的0.15 M NaCl中的腐蚀行为，并将其防护能力与CP-Ti和Ti-6Al-4V合金进行比较，以确定它们是否适合种植牙应用。 CP-Ti、Ti-15Mo 和 Ti6Al-4V 合金在含有 0.03 M NaF 的 0.15 M NaCl 中在 200 mV vs. SCE 下的稳态电流密度分别为 1、2 和 6 mu A/cm(2)，这表明它们在口腔环境中可能存在的电位范围内都可以提供更好的耐腐蚀性。 (C) 2010 Elsevier Ltd. 保留所有权利。
The corrosion behaviour of Ti-15Mo alloy in 0.15 M NaCl containing 0.01, 0.03, 0.06 and 0.5 M NaF is evaluated and its protective ability is compared with that of CP-Ti and Ti-6Al-4V alloy, to ascertain their suitability for dental implant application. The steady state current density of CP-Ti and, Ti-15Mo and Ti6Al-4V alloys in 0.15 M NaCl containing 0.03 M NaF at 200 mV vs. SCE is found to be 1, 2 and 6 mu A/cm(2), respectively, which indicate that all of them could offer a better corrosion resistance in the potential range that could exists in the oral environment.
