Purpose: This study was to observe characteristic of metal oxidation and bonding strength according tocomposition of Ni-Cr alloy for porcelain fused to metal crown. The three kinds of Ni-Cr alloy with differentcomposition ratio of parent metal were observed general properties and chemical properties of each alloy surface andmeasured the shear bonding strength between ceramic and each alloys. The aim of study was to suggest the materialfor design of parent metal’s composition ratio to development of alloy for porcelain fused to metal crown. Methods: The three kinds of alloy as test specimen was Ni(59wt%)-Cr(24wt%), Ni(67wt.%)-Cr(16wt.%) alloyand Ni(71wt%)-Cr(12wt%)alloy. The oxide on surface was observed by EDX. And the shear test was performed byMTS. Results: The surface property and oxide characteristic analysis of oxide layer, weight percentage of Element Owithin Ni59Cr24 alloy measured 23.03wt%, Ni67Cr16 alloy measured 21.13wt% and Ni71Cr12 alloy was measured48.55wt%. And the maximum shear bonding strength was measured 58.02Mpa between Ni59Cr24 alloy and vintagehalo(H2 group). Conclusion: The surface property and oxide characteristic three kind of Ni-Cr alloy was similar. and shearbonding strength showed the highest bonding strength in H2 specimens.
