Metalized materials for Si3N4 ceramic surface and preparation method as well as brazing technique
The invention discloses metalized materials for Si3N4 ceramic surface and a preparation method as well as brazing technique. Silver-based materials are of powder particles, which are prepared from the following components in percentage by weight: 20 to 25 percent of Cu, 3 to 5 percent of Ti, 2 to 3 percent of Ni, 0.1 to 0.3 percent of Ce, 0.2 to 0.3 percent of Sc, 0.5 to 0.6 percent of Re, and the balance of Ag; a particle size of the Ag, the Cu, the Ti and the Ni is 40 mu. m to 55 mu. m, the particle size of the Ce, Sc and Re is 15 mu. m to 25 mu. m. The silver-based materials provided by the invention are of flexible fibrous metal cloth materials, which are prepared by the pressure roller under the effect of a special adhesive; the composition of Ag-base alloy materials are uniform and the Ag-base alloy materials have a certain adhesive property; the Ag-base alloy materials are conductive to the local binding of ceramic parts in various complex parts, can ensure that the metalized materials for the Si3N4 ceramic surface do not fall off and the distribution of the surface metal is uniform under the condition of brazing, are conductive to the atomic diffusion and the interfacial reaction in a brazed connection process, can improve the wettability of the metalized materials for a surface, and are conductive to a good connection between the ceramic and a metal.
