を提供する。Contains active metals (CTr, Zr, etc.) and has good corrosion resistance.
To provide a brazing material for ceramic bonding that can be bonded at 000°C or less.
従来、セラミックスの接合には、Ａｇ−Ｃｕ−Ｔｉ＋Ａ
Ｉ Ｓｉ＋ Ｔｉ−ＩＪ＋などが用いられていた。Conventionally, Ag-Cu-Ti+A was used for joining ceramics.
ISi+ Ti-IJ+ and the like were used.

、本発明は、従来のこのような欠点を解決するため、耐
食性が良く、接合温度１０００’ｃ以下となるような、
ろう材を提供することを目的としている。Conventionally used Ag-Cu-Ti and Al-5i have the disadvantage of being corroded by salt water, artificial sweat alkali, acid, etc. Although TiNi is resistant to corrosion, it has the disadvantage that the bonding temperature is as high as 1200°C or higher, and the ceramic binder melts. Therefore, the present invention aims to solve these conventional disadvantages. Good corrosion resistance and a bonding temperature of 1000'C or less.
The purpose is to provide brazing filler metals.
耐食性の良い成分を主体とし、融点の低い金属を含むこ
とにより、耐食性が良く融点の低いろう材を得る。A brazing filler metal with good corrosion resistance and a low melting point can be obtained by mainly containing components with good corrosion resistance and containing metals with a low melting point.
Ａｕを主成分とすることにより、耐食性鏡検でき、Ａｇ

By including , Cu, and Zn, the junction temperature can be increased to 100%.
The temperature can be lowered to 0°C or less.
以下にこの発明の詳細な説明する。 This invention will be explained in detail below.
表−１に、本発明の実施例試料の成分を示す。Table 1 shows the components of the example samples of the present invention.
試料１〜６の耐食性、ろう接強度を、表−２に示す。比
較として従来のろう材の値を併記した。The corrosion resistance and brazing strength of Samples 1 to 6 are shown in Table 2. For comparison, the values for conventional brazing filler metals are also listed.
表−２から明らかなように本発明による試料１〜６は、
従来のろう材と同等以上の接合強度を有し、更に耐食性

順に悪くなっている。）ここでＡｕの下限４０％、 Ａ
ｇの上限２４％、 Ｃｕの上限４０％。As is clear from Table 2, samples 1 to 6 according to the present invention are
It can be seen that the bonding strength is equal to or higher than that of conventional brazing filler metals, and it also has excellent corrosion resistance. (Displayed in 5 stages, getting worse in the order of 1 to 5.) Here, the lower limit of Au is 40%, A
Upper limit of g is 24%, upper limit of Cu is 40%.
Ｚｎの上限１０％は、耐食性の点から、Ａｕの上限８０
％はコスト面から、Ａｇの下限２％、 Ｃｕの下限１％
は、ろう材の融点を１０００°Ｃ以内に（■えるという
点から設定した。The upper limit of 10% for Zn is the upper limit of 80% for Au from the viewpoint of corrosion resistance.
From a cost perspective, the lower limit for Ag is 2%, and the lower limit for Cu is 1%.
The melting point of the brazing filler metal was set within 1000°C (■).
表−３は、他の実施例試料の成分組成を示す。Table 3 shows the component compositions of other example samples.
表−４は、試料７〜１０の耐食性、ろう接強度を示す。Table 4 shows the corrosion resistance and brazing strength of Samples 7 to 10.
ここで、Ｎｉは、耐食性の向上を狙って、加えたもので
類似成分試料１，２．６と比較して、更に耐食性が良く
