ろう材の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a composite brazing filler metal for joining ceramics to ceramics, ceramics to metals, and metals to metals.

クスと金属の接合には、Tiの活性な性質を利用
する為にTiを含有したろう材が使用されている。(Prior art and its problems) In general, a brazing filler metal containing Ti is used to bond ceramics to ceramics and ceramics to metals in order to take advantage of the active properties of Ti.
しかし、Tiを含有するろう材は、脆い金属間

困難で、十分な接合強度が得られにくく、実用に
供しにくい。 However, titanium-containing brazing filler metals form brittle intermetallic compounds, making it difficult to plastically process them into plate or linear shapes. In order to prevent the formation of brittle intermetallic compounds, a method has been adopted in which Ti and brazing filler metal are bonded together and used as a composite brazing filler metal, but since Ti is extremely active, it is easy to form a film. It is difficult to bond with brazing filler metal, and it is difficult to obtain sufficient bonding strength, making it difficult to put it into practical use.

At least one type of plating of Ag, Ni, Pd 2~
This method is characterized by applying a 20 μm coating, then casting a dissimilar metal onto the plated surface, and then plastic working this into the desired shape.

成し、ろう接作用の働きをさせる為である。 In the method for manufacturing a composite brazing filler metal of the present invention, Ti,
The reason why Ti alloy, Zr, or Zr alloy bars or plates are plated by 2 to 20 μm is that active Ti and Zr are heated by the heat of the molten metal during casting of dissimilar metals, and are exposed to O 2 ,
This is to prevent absorption of N 2 and 2. If the gas is less than 2μ, the gas will pass through the plating film and react with Ti and Zr.
This is because if it exceeds this, the plating processing time becomes longer and the cost increases, but the effect remains the same. The reason why we chose Au, Ag, Ni, and Pd as plating materials is that they are scientifically stable and can be easily bonded to dissimilar metals. Ti plated,
The reason why dissimilar metals are cast into bars or plates of Ti alloy, Zr, or Zr alloy is that when used as a composite brazing filler metal, it easily forms a brazing composition containing Ti and Zr, which improves the brazing effect. It is to make them work.

面にTiとCuの金属間化合物が作られた為である。Conventional example 2 After sandblasting both sides of a Ti plate with a thickness of 10 mm, width of 200 mm, and length of 300 mm, and pickling with fluoride chemicals, this was placed in the center of the mold and heated in a high frequency furnace with BAg-8 (Ag). -Cu28%) was melted and BAg-8 was cast on both sides of the Ti plate. This cast ingot had a thickness of 19 mm, a width of 200 mm, and a length of 300 mm, and when it was rolled, BAg-8 peeled off from both sides of the Ti plate. This is because Ti diffuses so quickly that an intermetallic compound of Ti and Cu is created at the interface.
