牙科用金属及合金的耐蚀性能

Corrosion resistance of dental metal & alloy

从模拟试验液中溶出的离子量方面,比较了牙科用金属及合金的耐蚀性能。讨论了牙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。概述了近年开发的牙科用新型合金的耐蚀性能。

This paper reviewed the corrosion resistance of various dental alloys evaluated in the light of their released ions in experiments, and showed the examples in which original corrosion resistance was lowered by the factors such as casting . polishing and contact with other metals. The trends of the dental alloy development by the new gold alloys with safety to organism were discussed.
