[Industrial Application Field] The present invention relates to a brazing filler metal for brazing titanium or titanium alloy materials (hereinafter simply referred to as titanium materials), and in particular to a brazing filler metal for use in brazing titanium dental instruments. Regarding. [Prior art] Due to its excellent properties, titanium material is used in aircraft,
Its use is progressing in various industrial fields including nuclear power. On the other hand, in recent years, this titanium material has improved its corrosion resistance,
It has become known that in addition to having excellent mechanical strength and low specific gravity, it also has compatibility with living organisms and properties that are harmless to living organisms, and its use as a medical material is progressing. There is. In particular, the use of titanium materials for dental technology (dental crowns, denture bases, etc.) is being actively promoted. However, titanium materials are highly active and easily oxidize at high temperatures, so when soldering is performed, such as in the manufacture of dental technology, it must be done in a vacuum or in an inert gas atmosphere. This has been a major hindrance to the manufacture of titanium dental instruments. For this reason, the present inventors
He first developed an infrared soldering device that could be put to practical use in soldering titanium dental instruments, and filed an application (Utility Application No. 148702, 1983).
No.). [Problems to be Solved by the Invention] By the way, titanium materials were brazed together using the above-mentioned infrared soldering device and a commercially available general industrial titanium brazing filler metal and flux. , Zn and Sn contained in the brazing filler metal and flux are generated as fumes, and these fumes adhere to the inner circumferential surface of the infrared soldering device, making it difficult to perform a good soldering job. The brazing filler metal melts (cutting into the base metal), damaging the shape of the titanium dental instrument and resulting in a rejected product, or it may be due to a compound forming at the joint, but the bond remains stable. Strength (30Kg
f/mm 2 or higher) was not obtained and the problem was observed. Therefore, in view of the above-mentioned problems, the present invention enables soldering without using flux, avoids the use of Ni, which has become a problem in recent years due to its toxicity to living organisms, and furthermore, uses materials such as Zn and Sn. Ti containing as few components as possible
The basic component is a ternary system consisting of -Cu-Pd, and in addition, it can stably achieve a joint strength of 30Kgf/mm2 or more by brazing, and has good flowability with respect to titanium materials. The purpose of this project is to develop and provide a brazing filler metal for titanium materials that has approximately the same color as titanium materials. [Means for Solving the Problem] In order to achieve the above object, the brazing filler metal for titanium material according to the present invention contains Ti: 25 to 50 wt%,
It consists of Cu: 15 to 40 wt%, Pd: 15 to 40 wt%, and inevitable impurities. The brazing filler metal is pure Ti material or Ti-Pd
It may be made of a composite material in which an alloy material and a Cu-Pd alloy material are laminated. [Function] The brazing filler metal for brazing titanium materials according to the present invention has good flow properties with respect to titanium materials, has substantially the same color as titanium materials, and is harmless to living organisms.
Further, in soldering, it is possible to perform soldering without using flux, and a stable and high-strength joint can be obtained. Next, the reason for specifying each component will be explained. Ti is 25wt% in combination with Cu and Pd
If it is less than 50 wt %, the melting of the brazing material into the titanium material is unavoidable, and a stable and high-strength joint cannot be obtained, and if it exceeds 50 wt %, the flowability will be significantly reduced. Cu is 15wt% in combination with Ti and Pd
If the content is less than 40 wt%, the flowability will decrease, and if it exceeds 40wt%, the flowability will be too good, making it difficult to build up the desired build-up, and the color will be less similar to that of the titanium material. Pd is 15wt% in combination with Ti and Cu
If it is less than 40wt%, the flowability will be too good and it will be difficult to build up the desired thickness, and if it exceeds 40wt%, the flowability will decrease. Incidentally, the unavoidable impurities in the present invention refer to components that are unavoidable in the production of the brazing material, but the content of these should be reduced as much as possible due to the effects on fumes and living organisms during soldering. It is preferable. [Examples] Examples of the present invention will be described below. Cu obtained by vacuum melting pure Cu and pure Pd as raw materials
- Rolling Pd alloy cast sides and commercially available pure Ti and Ti-Pd alloy plates into sheet materials of various thicknesses,
The rolled sheet materials were combined, and the combined materials were laminated and rolled to a predetermined thickness of 0.25 mm to obtain a composite brazing material having the components shown in the table below. Using these brazing materials, diameter 3mm x length 50mm
Pure titanium rods are soldered together in an argon atmosphere using a soldering method, and the flowability during soldering is improved.
The penetration of the brazing filler metal into the base metal and the color tone were observed.
For those with good observation results, a tensile test was further conducted on the brazed parts. These observation results and tensile test results are also shown in the table below.

As mentioned above, the present invention is a ternary titanium brazing filler metal consisting of Ti-Cu-Pd, and therefore has good flowability to titanium materials and is suitable for soldering to titanium materials. It is harmless to living organisms, with no material penetration, almost the same color as titanium material, and no Ni content. Further, when soldering, it has the advantage that soldering can be performed without using flux, and a soldered part with high strength can be stably obtained.
