[Bonding strength between porcelain and gold alloys. (2) The effects of iron, indium and tin (author's transl)].

Ten kinds of alloys were prepared for testing by addition of 0-0.75 wt% iron, indium and tin (total amount 0.75 wt%) to base alloy, 88 Au-6 Pt-5 Pd-1 Ag. Opaque porcelain (Ceramco Inc.) was fused to these alloys according to the manufacturer's directions. The bonding strength was determined by the shear bond test that had been described in the preceding paper and the effects of the trace elements were examined.
