ラッドするかしていた。(Prior art and its problems) Conventionally, when Ti-containing brazing filler metal is made into an alloy, an intermetallic compound is formed between Ti and the elements in the noble metal alloy, making plastic working difficult. The production method is to obtain alloy powder by atomizing molten metal, or to use a precious metal alloy as an intermediate layer and clad the surface with Ti, or vice versa, to use Ti as an intermediate layer and clad the surface with a precious metal alloy. Was.

。(Objective of the Invention) The present invention has been made to solve these problems, and has easy plastic workability, completes alloying in a short time during brazing, and has a uniform structure after becoming an alloy. Ti, which does not cause segregation to the extent that it has a negative impact on the bonding strength.
It is an object of the present invention to provide a method for producing a composite brazing filler metal.

押出またはスェージ、圧延。(Structure of the Invention) The method for producing a Ti-containing composite brazing filler metal of the present invention involves cutting a wire rod made by cratting Ti and a precious metal alloy into required dimensions, bundling the wire rods, repeating compression molding and sintering two or more times. After hot extrusion or swaging, rolling.

この工程を２回以上繰返すことによって、より一層微綱
な繊維状に分散したＴｉ入り複１合ろう材を作ることの
できるものである。1q of wire, tape, or plate-shaped material is made by drawing or the like. By passing through this step, Ti is uniformly dispersed in the noble metal alloy in the form of fibers in the state of a single metal, so that no intermetallic compound is formed between the elements in the noble metal alloy and Ti. Even if it forms, it is only a surface layer of Ti, so it can be easily drawn or rolled and finished into any size without losing its plastic workability. Moreover, by repeating this process two or more times, it is possible to produce a composite brazing filler metal containing Ti that is dispersed in the form of finer fibers.

う付後の組織も偏析が極めて少なく、接合強さも従来の
方法によるものと比較し著しく向上するものである。When Ti, Ti alloys, ceramics, etc. are brazed using this Ti-containing composite brazing material, Ti is uniformly dispersed in the precious metal alloy, so the molten alloy is completed in a short time, and the structure after brazing is Also, segregation is extremely low, and the bonding strength is significantly improved compared to conventional methods.
