| 内容記述 | Corrosion tests were conducted on 18K gold alloys, prepared with thirteen commercial plus-metal alloy specimens and immersed in 0.05% hydrochloric acid and 1% lactic acid for 7 days at 37℃. Quantitative analysis of the metal elements released in solutions was performed by I.C.P. method. The amounts of released metal was studied on the relation ship of alloying methods and casting methods. The results obtained were as follows: 1. Release of metal elements from 18K gold alloys (without zinc) is caused by copper oxide (Cu_2o), which was oxidized at alloying and casting in the atomsphere. 2. Tamman's discorrosion rule is ineffective on melting metal. Only deoxidization materials pprevent oxidation of gold alloys. 3. The oxides produced at melting time mix in castings, without exception. 4. If mixed oxides are unstable, the release of metal elements rise 100-10000 fold. 5. All dental castings should be cast in the total absens of oxygen. If impossible, then all dental alloys should contain deoxidization materials. | |||||||
