NOVEL BRAZING CONCEPT |
摘要 |
The present invention relates to an intermediate product for joining and coating by brazing comprising a base metal and a blend of boron and silicon, said base metal having a solidus temperature above 1040° C., and the intermediate product has at least partly a surface layer of the blend on the base metal, wherein the boron in the blend is selected from a boron source, and the silicon in the blend is selected from a silicon source, and wherein the blend comprises boron and silicon in a ratio of boron to silicon within a range from about 3:100 wt/wt to about 100:3 wt/wt. The present invention relates also to a stacked intermediate product, to an assembled intermediate product, to a method of brazing, to a brazed product, to a use of an intermediate product, to a pre-brazed product, to a blend and to paint. |

1. A blend for brazing of joints in products of base metals and/or for coating of products of base metals, which base metal has a solidus temperature above 1040° C., which blend comprises
boron, wherein the boron is selected from a boron source; silicon, wherein the silicon is selected from a silicon source; and at least one binder selected from the group consisting of solvents, water, oils, gels, lacquers, varnish, and binders based on monomers and/or polymers, wherein the boron and silicon of the blend are present in a ratio of boron to silicon within a range from about 3:100 wt/wt to about 100:3 wt/wt. |
