Description
【発明の詳細な説明】 (産業上の利用分野) 本発明は、パラジウムろう合金の改良に関する。Description: FIELD OF THE INVENTION The present invention relates to improvements in palladium brazing alloys.
(従来の技術) 一般に航空機器等に用いるTi又はTi合金より成る部品
等をろう付けする為のろう合金としては、ニッケルろ
う、金ろう、パラジウムろうが主に用いられている。(Prior Art) In general, nickel brazing, gold brazing, and palladium brazing are mainly used as brazing alloys for brazing parts or the like made of Ti or Ti alloy used for aviation equipment and the like.
(発明が解決しようとする課題) ところで、上記のろうを用いてろう付けを行うと、ろ
う付け後の引張り強さが十分ではなく、Ti及びTi合金よ
り成る部品等の薄肉化や継手形状の設計が難しくなると
いう問題があった。(Problems to be Solved by the Invention) By the way, when brazing is performed using the above braze, the tensile strength after brazing is not sufficient, and thinning of parts such as Ti and Ti alloys and the formation of joints are not performed. There was a problem that the design became difficult.
そこで本発明は、Ti又はTi合金の部品等をろう付けし
た際、ろう付け後の引張り強さを十分なものにできるパ
ラジウムろう合金を提供しようとするものである。Accordingly, an object of the present invention is to provide a palladium brazing alloy that can have a sufficient tensile strength after brazing when brazing a Ti or Ti alloy component or the like.

上が見られず、また15重量%を超えるとパラジウムろう
合金の塑性加工性が著しく低下するからである。In the palladium brazing alloy of the present invention, the reason why cobalt or nickel and cobalt or iron and cobalt are contained in the copper-palladium alloy is that the brazing portion such as Ti or Ti alloy parts has Cu-Ti, Pd-Ti This is for suppressing the formation of the intermetallic compound. Further, the content is set to 5 to 15% by weight. When the content is less than 5% by weight, no improvement in the tensile strength of the brazed portion is observed, and when the content exceeds 15% by weight, the plastic workability of the palladium brazing alloy is remarkably increased. It is because it falls.

が向上する。(Function) When a part or the like made of Ti or Ti alloy is brazed by the palladium brazing alloy having the above-described structure, an intermetallic compound of Cu-Ti or Pd-Ti is generated at a brazed part by iron, nickel, cobalt, or the like. Is suppressed, and the tensile strength of the brazed portion is improved.
