钛材料在口腔生物环境中腐蚀的研究进展

Research development of corrosion of titanium in the oral bioenvironment

钛材料在口腔医学领域的应用越来越普及,但钛材料在口腔中的腐蚀却是亟待解决的问题。钛材料的腐蚀与口腔生物环境中递质的变化以及口腔的咀嚼活动参与密切相关。下面就钛及其合金在pH值、氟化物和蛋白质以及温度变化等口腔生物环境中的腐蚀研究进展作一综述,以期为钛及其合金耐腐蚀性能的提高提供参考。

Titanium and its alloys are used more and more widely in the field of dental clinic. But the corrosion of titanium and its alloys in the oral environment is still a concern that has to be solved. The corrosion behaviors are closely related to the change of oral bioenvironment and mastication. This article presents a research statue of corrosion of titanium and its alloys in the oral bioenviroment where the value of pH, fluoride, protein and the temperature change a lot, thus gives us a reference to improve the corrosion resistance of titanium and its alloys.
