✦ Synopsis

The effect of small In additions on oxide structure and porcelain adherence to Au-Pd alloys was studied. In was oxidized internally as In203. No uniform external oxide layer could be seen. Small In addition (1 at%) did not have any detectable effect on porcelain adherence (~12 MPa), whereas higher In concentration (5 at%) caused significant increase in bond strength (~,26 MPa). This increase was probably a result of higher In203 concentration at the surface.
