Abstract

A cast-soldering method was used for the keepers of magnetic attachments. However, there have been few studies concerning the effects of the cast-soldering method on keepers. In this study, this cast-soldering method was investigated by changing the mold temperature.<BR>Two commercially available keepers and a 12% Au-Ag-Pd casting alloy were used. Cast-soldering was performed at mold temperatures of 600, 700 and 800°C for 30 minutes. After cast-soldering, the interface between the keeper and the casting alloy was observed by light microscopy and scanning electron microscopy and analyzed with an X-ray electron microprobe.<BR>Microscopic observation revealed a black layer between the keeper and the casting alloy in all specimens. Scanning electron microscopy and X-ray electron microprobe analysis indicated that the black layer was composed of an oxidation layer with Fe and a gap. The black layer was larger at lower mold temperatures.<BR>The findings suggested that it is important to keep the mold at a proper temperature.
