Ceramic metallization is a specialized process that involves the deposition of a metallic layer onto the surface of a ceramic substrate, enhancing its wettability for subsequent brazing applications.
The procedure typically begins with thorough cleaning and preparation of the ceramic surface. This is followed by the application of a metallization coating, comprised of a blend of molybdenum/manganese or molybdenum/manganese/tungsten, using techniques such as needle painting, brushing, spraying, or screen-printing, and then sintering the coated ceramic to permanently bond the metal layer. The final product is a component that is ready for brazing into a hermetic assembly.
