Product Description
High Vacuum-tight Ceramic-to-metal
1.Description
Metallized ceramics is to firmly adhere a layer of metal film on the surface of the ceramic to realize the combination between the ceramic and the metal, so that it has both the characteristics of ceramics and the properties of metal. There are various ceramic metallization processes such as molybdenum-manganese sintering method, gold electroplating, copper electroplating, tin electroplating, nickel electroplating, vacuum plating and so on.
