摘　　要：目的:探讨烤瓷用Ni-Cr合金金瓷结合的机制。方法:制备Ni-Cr合金金瓷试样,对金瓷界面采用扫描电镜、X射线衍射仪观察元素的扩散情况及界面反应产物。结果Ni-Cr合金与陶瓷界面处有元素的相互扩散,并有一连续的反应薄层,界面反应产物主要是AlNi3及SnCrO的复合氧化物。结论:金属与陶瓷界面反应产物AlNi3及SnCrO的复合氧化物同时具备有金属性和陶瓷性,实现了金瓷之间的可靠结合。Objective：To investigate the mechanisn of interface reaction between porcelain and fused Ni-Cr alloy.Methods：The metal-porcelain samples were prepared and analyzed by using electronic scanning microscope and X-ray diffractometer.Resultant was observed at metal-porcelain interface.Results：The main elements of porcelain and metal diffused reciprocally.AlNi3 and SnCrO compound oxide were produced,a narrow reaction layer were examined in the interface.Conclusion：The main elements diffused well.AlNi3 and SnCrO compound possessed the qualities of metal and porcelain.There is a good bonding strength between Ni-Cr alloy and porcelain.
