[Investigations of Pd-Ag alloy for porcelain fusing. (Part 1) Bond strength (author's transl)].

For the purpose of developing the Pd-Ag alloys for porcelain fusing, indium and/or tin were added to Pd-Ag alloys (70, 60 and 50 wt% Pd) and nine kinds of testing alloys for porcelain fusing were prepared. The bond strength with Ceramco porcelain was measured. The test-pieces for bond strength measured were prepared by press or condensing method. The bond strength was measured by "pull-out method" developed by Iwama. The maximum bond strength (230 kgf/cm2) was obtained 54 wt% Pd-36 wt% Ag-5 wt% In-5 wt% Sn alloy.
