Abstract
The effect of ceramic metallization process on the performance of vacuum interrupter was researched by X-ray thickness test, metallographic analysis, tensile strength test and air tightness test. Electroplating Ni and coating Ni metallization processes were used in this research. The thickness of electroplating Ni is 3.5μm-6μm, and that of coating Ni is 4μm-6μm. The Ni layers of electroplating Ni and coating Ni are both continuous, but electroplating Ni is not uniform. A little Ni layer can be seen from electroplating Ni ceramic after vacuum brazing. The tensile strength difference of standard tensile pieces between them is little. The air tightness difference of vacuum interrupter between them is not obvious.
