Thick Film Metallized Ceramic

Alumina-Metallized-Ceramic-Parts

Innovacera can provide Thick Film Metalizing Ceramics. Metalization is a coating of metal material with good adhesion on the ceramic.This can be followed by a barrier diffusion layer of electrolytic pure Nickel (Ni). The third layer of gold (Au) or other precious metal, results in a tightly sealed ceramic to metal assembly ready for the soldering or brazing process. Unmetalized sections of the part can also be glazed.
