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 I
A method of testing the tensile strength of the porcelain-gold bond has been developed. Tensile strengths of the bond are improved primarily by the formation of an oxide layer on the gold before baking the porcelain and not by the degree of gross surface roughness. The oxide layer may act either as
Porcelain fracture at the interface between metal and porcelain is one of the most common clinical failures. For the clinical longevity, metal-ceramic prostheses must have satisfactory bond strength of the metal structure to porcelain. In this in-vitro study, to evaluate the effect of mechanical tex
