Alloys added 2, 4 and 6 wt% Mn, Mo, Si, Sn, Ta and Ti to 80 wt% Ni-20 wt% Cr alloyand no-added 80 wt% Ni-20 wt% Cr alloy were prepared and casted to obtain the test specimens 3 mm in diameter 25 mm in length. Ceramco porcelain (B.F. Vacuum Porcelain) was fused to each of these specimens, and the bond strength was measured by the pull-out method which applies shear stress to the metal/porcelain interface to investigate the effect of each addition element. The test results may be summarized as presented below. 1) The bond strength between the 80 Ni-20 Cr alloy and the porcelain was 182 +/- 14 kg/cm2. 2) Of the six kinds of addition elements, it was Mo, Sn, Ta and Ti that increased the bond strength. 3) The bond strength between the alloy added 6 wt% Ti to the 80 Ni-20 Cr alloy and the porcelain was 319 +/- 8 kg/cm2, which was increased by about 75% over the strength between the 80 Ni-20 Cr alloy and the porcelain.
向80 wt% Ni - 20 wt% Cr合金中添加2 wt%、4 wt%和6 wt%的锰（Mn）、钼（Mo）、硅（Si）、锡（Sn）、钽（Ta）和钛（Ti），制备未添加的80 wt% Ni - 20 wt% Cr合金，并将其铸造以获得直径3 mm、长度25 mm的试样。将Ceramco烤瓷（B.F.真空烤瓷）熔合到每个试样上，并通过拔出法测量结合强度，该方法对金属/烤瓷界面施加剪切应力，以研究每种添加元素的影响。测试结果总结如下：1）80 Ni - 20 Cr合金与烤瓷之间的结合强度为182±14 kg/cm²。2）在六种添加元素中，钼、锡、钽和钛提高了结合强度。3）向80 Ni - 20 Cr合金中添加6 wt%钛的合金与烤瓷之间的结合强度为319±8 kg/cm²，比80 Ni - 20 Cr合金与烤瓷之间的强度提高了约75%。
