。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a brazing material for brazing titanium or titanium alloy materials (hereinafter simply referred to as titanium materials), and in particular, to a brazing material for brazing titanium dental materials. Regarding the brazing filler metal used when making contact.
チタン材は、その優れた特性のため航空機や、原子力等
を始め種々の工業分野で利用が進められている。Due to its excellent properties, titanium material is being used in various industrial fields including aircraft and nuclear power.

にチタン材を利用することが積極的に進められている。On the other hand, in recent years, it has become known that this titanium material has properties such as corrosion resistance, excellent mechanical strength, and low specific gravity, and also has properties that are compatible with living organisms and are harmless to living organisms. As a result, its use as a medical material is also progressing. Among other things, dental technology (dental crowns, denture bases, etc.)
The use of titanium materials is being actively promoted.
ところが、チタン材は、高温では活性が高く容易に酸化

８７０２号）した。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 these reasons, the present inventors 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.
No. 8702).

The basic component is a ternary system consisting of u-Pd, and in addition, the shear strength of the lap joint by brazing is 30 kg.
To develop and provide a brazing filler metal for titanium materials that can obtain f/m+*" or more, has good flow properties for titanium materials, is harmless to living organisms, and has approximately the same color as titanium materials. The purpose is to

そして、他の一つは、Ｐｄ ： ２０〜４０ｗＬ％、Ａ

、且つ、生体に対し無害である。The brazing filler metal for titanium material according to the present invention has good flow properties with respect to titanium material, has substantially the same color as titanium material, and is harmless to living organisms.
４た、ろう接に当たっては、フラックスを使用せずにろ
う接し得ると共に、高強度のろう接部が得られる。4. In soldering, it is possible to perform soldering without using flux, and a high-strength soldered part can be obtained.
次に、各成分の特定理由を説明する。Next, the reason for specifying each component will be explained.

るので、Ｐｄ ： ３０〜４０−１％およびＡｇ ：
６０〜７〇ｗｔ％とした。In the case of a binary system of Pd and Ag, if Ag is less than 60 wt%, a stable and high-strength brazed joint cannot be obtained in combination with Pd even if the amount of Pd added exceeds 40 wt%. Furthermore, if ag exceeds 70wt%, even if the addition amount of Pd is less than 30wt% in combination with Pd, a stable and high-strength brazed joint cannot be obtained, and A
When the amount of g or Pd increases, the flowability with respect to titanium material hardly changes, but the almost same color system with titanium material becomes weaker, so Pd: 30 to 40-1% and Ag:
It was set at 60 to 70 wt%.
また、ＰｄとＡｕとＡｇとの三元系の場合、Ａｇが６０

よびＡｇ：６０〜７０ｗｔ％とした。In addition, in the case of a ternary system of Pd, Au, and Ag, Ag is 60
- Below 1%, in the combination of Pd and Au,
Even if the addition amount of Pd exceeds 40wt% and/or the addition amount of Au exceeds 10wt%, a stable and high-strength brazed joint cannot be obtained. In combination with Au, the amount of Pd added is 20w.
Even if the additive amount of U is less than 10 wt%, a stable and high-strength brazed joint cannot be obtained, and Ag or P
As the amount of d increases, the flowability to titanium material will hardly change, but the almost same color system with titanium material will fade, so Pd
: 20 to 40 wt%, Au: 10 wt% or less, and Ag: 60 to 70 wt%.
尚、本発明における不可避的不純物とは、ろう材の製造

有量を減少させる方が望ましい。Incidentally, in the present invention, unavoidable impurities refer to components that are unavoidable in the production of brazing filler metals, but it is recommended that the content of these impurities be reduced as much as possible due to the fumes of wax entertainment and the effects on living organisms. is desirable.
以下に、本発明の実施例について説明する。 Examples of the present invention will be described below.
原料を種々配合して真空溶解し、得た鋳片をシート状に
圧延して厚さ０．２ｍｎ＋の下表に示するう材を得た。Various raw materials were blended and vacuum melted, and the obtained slab was rolled into a sheet to obtain a filler material having a thickness of 0.2 mm+ as shown in the table below.
