Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、摩擦溶接方法に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a friction welding method.
Ｃ従来の技術とその問題点〕
従来から、二つの金属部材、即ち母材を突合せて相対回
転運動をさせ、その接触面に発生する摩擦熱を利用して
圧接する摩擦溶接方法が知られている。C. Conventional technology and its problems] Conventionally, a friction welding method has been known in which two metal members, that is, base metals, are butted against each other and subjected to relative rotational motion, and the frictional heat generated on the contact surfaces is used to press them together. There is.
具体的には、大気中において母材の一方を固定し、他方
を駆動系に結合された軸に取イ」けて一定回転数で回転
し続け、軸方向にアプセット推力を与えて加圧しつつ摩
擦させて、摩擦部が適温になったとき、ブレーキによっ
て回転を急停止させて行われる。このとき摩擦部の温度
は、同種材間の圧接ではその材料の融点直下まで上昇し
ており、また異材圧接の場合には、融点の低い方の母材
の融点あるいは両川材の共晶点に達しているものと推察
されている。Specifically, one side of the base material is fixed in the atmosphere, the other is placed on a shaft connected to a drive system, and continues to rotate at a constant rotational speed while applying pressure by applying an upset thrust in the axial direction. When the friction part reaches the appropriate temperature, the brake is used to suddenly stop the rotation. At this time, the temperature of the friction part rises to just below the melting point of the materials in pressure welding of similar materials, and in the case of pressure welding of dissimilar materials, it rises to the melting point of the base material with the lower melting point or the eutectic point of the Ryogawa materials. It is assumed that this has been achieved.
しかしながら、圧接作業は、大気中で行われるため、母
材の接合面は酸化被膜で覆われており、その酸化被膜、
その他汚れなどを接合部から押し出す必要があるため、
押出されるばつの量も多く、そのはり取りに多大の労力
を要した。However, since the pressure welding work is performed in the atmosphere, the bonding surfaces of the base materials are covered with an oxide film.
Since it is necessary to push out other dirt etc. from the joint,
The amount of extrusion was large, and it took a lot of effort to remove the bulk.
また、特にチタンやジルコニウムなどの超耐熱金属材料
からなる異材継手の接合においては、酸化被膜の影響も
加わってアプセット＋ｆｆ力をより大きくする必要があ
った。Furthermore, especially when joining dissimilar metal joints made of super heat-resistant metal materials such as titanium and zirconium, it is necessary to further increase the upset +ff force due to the influence of the oxide film.
更に、酸化被膜や汚れなどにより圧接条件が一定せず、
接合強度に品質の不均一がみられた。Furthermore, the pressure welding conditions may not be constant due to oxide film or dirt, etc.
Inconsistency in bond strength was observed.
本発明は、かかる問題点に鑑みなされたもので、その目
的□は作業の高能率化を図りしかも高品質の継手を得る
ことができる優れた摩擦溶接方法を提供することにある
。The present invention has been made in view of these problems, and its purpose is to provide an excellent friction welding method that can increase the efficiency of the work and produce high-quality joints.
〔問題点を解決するための手段〕 、本発明の方法は
、二つの金属部材を相互の摩擦熱によって接合する摩擦
溶接方法において、上記金属部材を非酸化雰囲気中に存
在させ、該金属部材の接合面に生成された酸化被膜を除
去しに後、接合面を活性化させた状態で圧接するように
したことを要旨とする。[Means for Solving the Problems] The method of the present invention is a friction welding method for joining two metal members by mutual frictional heat, in which the metal members are placed in a non-oxidizing atmosphere, and the metal members are heated. The gist is that after removing the oxide film formed on the bonding surfaces, the bonding surfaces are pressed together in an activated state.
真空または不活性ガスで充満された非酸化雰囲気中で、
二つの金属部材からその接合面に生成された酸化被膜を
除去して、接合面を活性化させ、しかる後その状態で圧
接する。このため接合面から押出されるばりを皆無もし
くは極めて少量にすることができ、かつ、アプセット推
力も小さくできる。In a non-oxidizing atmosphere filled with vacuum or inert gas,
The oxide film formed on the joint surfaces of two metal members is removed to activate the joint surfaces, and then the two metal members are pressed together in that state. Therefore, the amount of burrs extruded from the joint surface can be eliminated or minimized, and the upset thrust can also be reduced.
本発明の摩擦溶接方法の一実施例を説明する。 An embodiment of the friction welding method of the present invention will be described.
円形断面からなる二つの金属部材をアルゴンガスで充満
されたチャンバ内に存在させ、チャンバ内で金属部材の
接合面をそれぞれ電圧を負荷した金属ブラシまたは炭素
ブラシなどにより電気的、機械的に削除して、接合面に
生成されている酸化被膜および汚れた付着膜を取り除き
、接合面を活性化させた状態で、二つの金属部材を突合
せて相対回転運動をさせ、その接触面に発生する摩擦熱
を利用して圧接し結合する。Two metal members with circular cross sections are placed in a chamber filled with argon gas, and the joint surfaces of the metal members are electrically and mechanically removed in the chamber using a voltage-loaded metal brush or carbon brush. After removing the oxide film and dirty adhering film formed on the joint surface and activating the joint surface, two metal members are butted against each other and subjected to relative rotational motion, and the frictional heat generated on the contact surface is removed. Use pressure to connect.
以上の如く本発明の方法は、非酸化雰囲気中で、接合面
に生成された酸化被膜を除去した後、接合面を活性化さ
せた状態で圧接するようにしたので、従来摩擦溶接では
、酸化被膜及び大気中から接合部への酸素ガスの混入に
より材質的にもろいために、非常に困難とされていたス
テンレス鋼とジルコニウム合金との接合も容易に行える
。また酸化被膜という摩擦溶接における障害物を除去す
ることで摩擦熱を従来よりも低くして圧接でき、セラミ
ックスと金属の接合も、ある限られたセラミックスにつ
いては割れることなく接合できる。その他、超耐熱金属
や活性金属、例えばジルコニウムやチタンと他種金属か
らなる異材継手の接合にも適している。As described above, the method of the present invention removes the oxide film formed on the joint surfaces in a non-oxidizing atmosphere, and then presses the joint surfaces in an activated state. It is now possible to easily join stainless steel and zirconium alloy, which was considered extremely difficult due to the brittle nature of the material due to the infiltration of oxygen gas from the coating and the atmosphere into the joint. In addition, by removing the oxide film, which is an obstacle during friction welding, pressure welding can be achieved with lower frictional heat than before, and ceramics and metals can be joined without cracking for a limited number of ceramics. In addition, it is also suitable for joining dissimilar metal joints made of super heat-resistant metals or active metals, such as zirconium or titanium, and other metals.
なお、上記実施例ではチャンバ内をアルゴンガスで充満
した場合について説明したが、チャンバ内の雰囲気は、
ヘリウムガス、窒素ガス等の不活性ガスまたは真空でも
よく、要は、金属表面に酸化被膜を生成しない非酸化雰
囲気であればよい。In the above embodiment, the case where the chamber was filled with argon gas was explained, but the atmosphere inside the chamber was as follows.
An inert gas such as helium gas or nitrogen gas or vacuum may be used, and in short, any non-oxidizing atmosphere that does not form an oxide film on the metal surface may be used.
その他、本発明の要旨を逸脱しない範囲内で種々変更し
得ることは勿論である。It goes without saying that various other changes can be made without departing from the spirit of the invention.
以上述べた如く本発明によれば、次のような優れた効果
を発揮する。As described above, according to the present invention, the following excellent effects are exhibited.
（１〉 接合部から押出されるばりの量を皆無もしく
は極めて少量にすることができる。(1) The amount of burrs extruded from the joint can be eliminated or extremely small.
（２） アプセット推力を小さくすることができる。(2) The upset thrust can be reduced.
（９接合面を活性化させた状態で接合するため、圧接条
件は常に一定にでき、接合強度の高い高品質の継手が得

継手の接合に適用できる。(4) Applicable to joining dissimilar metal joints made of super heat-resistant metals and materials with a loose range.
