alumina ceramics and metal materials
In practical applications, the sealing process of alumina ceramics and metal materials has become more and more popular. In order
to achieve perfect ceramic-metal sealing, the most important step is to do a good job of metallization of alumina ceramics which
will affect the final sealing effect. The methods of ceramic metallization mainly include:
– electroless Ni-P plating method
– electroplating Ni-P alloy method
– high temperature sintering by Ag(Ni) method
– Mo-Mn sintering method
– vacuum evaporation coating method
– vacuum sputtering coating method

Compared with the above several processes, the sputtering coating method is not only environmentally friendly, but also has a
simple process and low cost, and is the main development direction of the metallization process in the future. The quality of
ceramic metallization mainly depends on the quality of the ceramic itself and the metallization process. The specific influencing
factors include metallization formula, metallization temperature and holding time, metallization microstructure, metallization
coating thickness and coating method.
