Topography and distribution of trace surface metals (Sn, In) on alloys for porcelain-metal restoration: influence of surface treatment.
Gold alloys were given five different conditioning treatments prior to porcelain firing. The alloys were examined with a scanning electron microscope and energy dispersive X-ray analyzer. Only two of the alloys had tin and indium present; these were concentrated in particles partially fused to the alloy's surface.
