The purpose in the present project is to develop a new precious metal alloy for dental adhesive resin bonding. Three base metals, Sn, In, and Zn, were separately added to four metals, Au, Pd, Ag, and Cu, in order to obtain the binary alloys having superior durability for water at the adhesion interface.Indium addition of 15 wt% in the gold was effective to improve adhesion with 4-META resin. The alloy surface was analyzed to clarify the reasons by ESCA in the present study.Indium contents at the surface were higher than the bulk concentration of indium with increasing of indium addition. According to analysis of O ls spectrum, m both amounts of oxygen formed oxide and oxygen due to physisorbed water on the oxide were increased with increasing of indium addition. It is considered as the reason why indium addition leads to excellent adhesive ability.

本课题的目的是研制一种用于牙科粘接树脂粘接的新型贵金属合金。为了获得在粘接界面处具有上级的耐水性的二元合金，将Sn、In、Zn三种贱金属分别添加到Au、Pd、Ag、Cu四种金属中，在金中添加15wt%的铟，可以有效地提高与4-Meta树脂的粘接性。通过ESCA对合金表面进行分析，发现随着铟添加量的增加，合金表面的铟含量高于铟的体相浓度。根据氧谱分析，随着铟添加量的增加，形成氧化物的氧和由于氧化物上物理吸附的水而产生的氧的量都增加。这被认为是铟的添加导致优异的粘合能力的原因。
