Because the surface structures of metal and ceramic are totally different, it is impossible to weld metal and ceramic together directly. Therefore, we have used a special technique to weld them together which is called metallization. We first make a metallization level stick to ceramic surface which works as a transition layer. Then metal and ceramic can be welded together. This technique is the key to weld metal and ceramic. The metallization level can be obtained by sintering Mo-Mn paste on ceramic surface under high temperature of 1550 Celsius degree.

      Technical indicators

• Metallization level thickness: 17-22μm

• Nickel level thickness: 4-7μm（Ni coating）；7±1μm（Ni sintering）

• Average tensile strength: 2500Kgf/cm²
