The effect of Nb on interfacial bonding characteristics of Ni-Cr alloy for porcelain fused tometal crown (PFM) has been studied in order to investigate oxide layer. A specimens of Ni-Cralloy, which is 0.8mm in thickness, within the porcelain furnace of 1,000℃with four testssuch as air, vacuum, air for 5 minutes and vacuum for 5 minutes in order to examine an oxidebehavior of alloy surface generated by the adding of Nb to be controlled at a rate of 0, 1, 3and 5. Oxide film was observed form of the fired specimens with scanning electron microscope(SEM), and at the same time it measured Electron Probe Micro Analyzer (EPMA). The result of this study were as follows:1. Cr oxide film and Nb oxide film were observed from the surface of specimen to becontrolled at a rate of Nb 1%.2. Nb oxide film was observed from the interface of specimens to be controlled at a rateof Nb 1% and 3%.3. The stability of oxide films that treated in air were more stable than treated under vacuum.
