口腔科用生物材料的耐腐蚀性能

Corrosion resistance of stomatological biomedical materials

本文从模拟试验液中溶出的离子量方面,比较了口腔科用金属及合金的耐蚀性能,讨论了口腔科用金属及合金在成型及使用过程中其耐蚀性能下降的因素,如铸造、研磨和异种金属间的接触等。概述了近年来开发的口腔科用新型合金的耐蚀性能。

This paper reviews the corrosion resistance of various dental alloys evaluated in the light of their released ions in experiments,and shows the examples in which original corrosion resistance is lowered by the factors such as casting,polishing and contact with other metals.The corrosion resistance of new dental gold alloys developed currently is also discussed.
