The metallization of ceramic surfaces is a process with high technical content. The specific influencing factors include metallization formula, metallization temperature and holding time, metallization microstructure, metallization coating thickness and coating method, etc.
The function of the metallization layer on the ceramic surface is to enhance or improve the surface properties of the product, such as oxidation resistance, wear resistance, corrosion resistance, and certain electrical, optical and tribological properties.
Standard types of the metalization
1. Alumina ceramic base + silver (Ag) plating directly
2.Alumina ceramic base + molybdenum (Mo/Mn) metallization
3.Alumina ceramic base + molybdenum (Mo/Mn) metallization + nickel (Ni) plating
4. Alumina ceramic base + tungsten (W) metalization + gold (Au) plating

The prime features of alumina metalized ceramics
1. High bonding/brazing strength with ideal vacuum tightness between the assembly
2. With diamond-like hardness to be 85 HRV and superb compressive strength
3. Great insulation strength and volume resistivity that fit for various high voltage high current applications
4. Chemical stability, anti-aging even if it works in a variety of harsh environments, free of rust forever.
5. Over 276 times wear resistance in comparison with stainless steel, it leads to a long service lifespan.
