Abstract
Purpose: This study was observation shear bonding strength by compositional change and firing step of a Ni-Cralloy for porcelain fused metal crown. The aim of study was to suggest the material for firing step of Ni71-Cr14alloy to development of alloy for porcelain fused to metal crown.
Methods: The test was on the two kinds of Ni-Cr alloy specimens. The surfaces of two alloys were analyzed byEDX in order to observe oxide characteristic. And the shear test was performed by MTS.
Results: The surface property and oxide characteristic analysis of oxide layer, weight percentage of Element Owithin Ni71Cr14 alloy measured 23.32wt%, and Ni59Cr24 alloy was measured 23.03wt%. And the maximum shearbonding strength was measured 58.02 between Ni59Cr24 alloy and vintage halo(H4 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 H4 specimens.
