팔라디움-은 합금의 금전착이 도재의 색조에 주는 영향에 관한 연구 = THE EFFECT OF GOLD ELECTRODEPOSITION ON PALLADIUM-SILVER ALLOY TO THE COLOR OF PORCELAIN

다국어 초록 (Multilingual Abstract)

This study was performed to investigate the effect of gold electrodepositoin on porcelain color of palladium-silver alloy. The specimens were made by firing porcelain on the metal plates cast respectively in Au-Pt alloy, and Pd-Ag alloy. In the case of Pd-Ag alloy specimens, porcelain were fired under three different conditions of the metal plate: 1) without gold coating, 2) firing opaque beforehand on one side, gold coating on the other side, 3) gold coating on both sides of the metal plate. Color change was measured with fiber-optic colorimeter(Model TC-6FX, Tokyo Denshoku Co., Japan). The obtained results were as follows: 1. In the group of firing opaque beforehand on one side and gold coating on the other side, there was no significant differences in their color in comparison to the color of the control group of the Au-Pt alloys. 2. In the group of gold coating on both sides on metal plate, there were no significant differences except their value to the group of firing poaque beforehand on one side and gold coating on the other side.
