【発明の詳細な説明】
（産業上の利用分野）
本発明は粉末冶金法により摺動性、耐摩耗性に優れた銅
合金粉末シートを母材に焼結接合した積層体に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a laminate in which a copper alloy powder sheet having excellent sliding properties and wear resistance is sintered and bonded to a base material using a powder metallurgy method.

れている。(Prior art) Conventionally, this type of alloy powder has been produced by depositing an alloy powder sheet using a Ni-based or Go-based self-fusing alloy powder and a retractable acrylic resin on a metal base material with a solvent such as toluene. It is known that the adhesive is applied after being moistened and then heated and fused in the atmosphere.

うな合金粉末シートは、母材の表面に比較的容易に合金
層を形成することができる。(For example, see Japanese Patent Application Laid-open No. 51-838343.) With such an alloy powder sheet, an alloy layer can be formed relatively easily on the surface of the base material.
（発明が解決しようとする課題）
しかし、このような合金粉末シートを加熱焼結する場合
、２００〜３００°Ｃの温度で合成樹脂が焼失し、接着
性が失われるため、母材が平らな上面にしか通用できず
、斜面や、湾曲面さらに下面に対しては滑りや落下など
により、合金層を形成することができなかった。(Problem to be Solved by the Invention) However, when heating and sintering such an alloy powder sheet, the synthetic resin is burned out at a temperature of 200 to 300°C and adhesiveness is lost, so the base material is flat. It was applicable only to the upper surface, and could not form an alloy layer on sloped surfaces, curved surfaces, or even the lower surface due to slipping or falling.

供するものである。Therefore, although Cu-3n-based, Cu-Zn-based, and powder sheets have been used as bearing materials, they have been produced as a single product and press-fitted, and the shape has been limited to cylindrical ones. In order to form an alloy layer on a product with a complex shape, it is manufactured by processing after casting by brazing, thermal spraying, or casting, but the manufacturing cost is high6.The present invention aims to solve this problem by using copper. A sintered laminate of alloy powder sheets is provided.

The rolled sheet is attached to the base material. In addition, by adding P as a Fe-P alloy (P: 27 to 30 Wt%) powder, we can remove the oxide film on the surface of the base material to be joined during sintering and keep it clean, and also remove Fe (including P). Cu-

A low melting point Pb solder is produced to improve wettability with the base material, thereby improving adhesion at low temperatures and bonding strength during sintering. (See FIG. 5) Furthermore, Pb improves the sliding properties and seizure resistance of the sintered laminate.
つぎに、本発明において、各成分の含有！（以下重量％
とする）を限定した理由を説明する。Next, in the present invention, the content of each component! (hereinafter weight%
We will explain the reason why we limited the following.
（ａ）Ｓｎの含有量
銅合金粉末中のＳｎの含有量が５％未満では、Ｐｂの蒸
発を抑えることができず、高密度で焼結することは難か
しい、一方１５％を越えると保形性が低下することから
、Ｓｎの含有量を５〜１５％と定めた。(a) Sn content If the Sn content in the copper alloy powder is less than 5%, the evaporation of Pb cannot be suppressed and it is difficult to sinter at high density. The Sn content was determined to be 5 to 15% since the shape property was decreased.
（ｂ）Ｚｎの含有量
Ｚｎは、銅合金の素地組成を決定し、靭性を確保するた
めにはα＋β型、β型とする必要がある。Ｚｎの含有量
が１０％未満ではα相が増加しβ相が減少して所望の耐
摩耗性を確保することができず、一方４３％を越えると
α相の析出により跪化し強度も低下することからＺｎの
含有量を１０〜４３％と定めた。(b) Zn content Zn determines the base composition of the copper alloy and needs to be α+β type or β type in order to ensure toughness. If the Zn content is less than 10%, the α phase will increase and the β phase will decrease, making it impossible to secure the desired wear resistance. On the other hand, if it exceeds 43%, the α phase will precipitate and the strength will decrease. Therefore, the Zn content was determined to be 10 to 43%.
（ｃ）Ｐｂの含有量
Ｐｂの含有量が１．０％未満ではＦｅとの濡れ性改善効
果が不十分でありかつ摺動時に燐化物の硬質粒子による
カジリを防止できず、一方ｌＯ％を越えると焼結体の強
度が実用強度２０ｋｇ ／ ｍ ｍ ”以下に低下する
ことがらＰｂの含有量を１．０〜１０．０％と定めた。(c) Pb content If the Pb content is less than 1.0%, the effect of improving wettability with Fe is insufficient and galling due to hard phosphide particles during sliding cannot be prevented. The Pb content was determined to be 1.0 to 10.0% since the strength of the sintered body would drop below the practical strength of 20 kg/mm'' if the Pb content was exceeded.
（ｄ）Ｐの含有量
Ｐの含を量が０．０５％未満では、母材との接合強度を
１１保できず、焼結体のフクレを防止することもできな
い、一方３．５％を越えると、焼結体の伸びは３％以下
になり、かつ摺動時の耐焼付性も低下することがらＰの
含有量を０．０５〜３゜５％と定めた。(d) P content If the P content is less than 0.05%, the bonding strength with the base material cannot be maintained or the blistering of the sintered body cannot be prevented. If it exceeds this, the elongation of the sintered body becomes 3% or less, and the seizure resistance during sliding also decreases, so the P content was set at 0.05 to 3.5%.
また、前記銅合金粉末８５〜９７％と合成樹脂バインダ
ー３〜１５％を混練、圧延し銅合金粉末シートとして母
材に貼着する。ここで合成樹脂の種類および量を限定し
た理由を説明する。Further, 85 to 97% of the copper alloy powder and 3 to 15% of the synthetic resin binder are kneaded and rolled to form a copper alloy powder sheet and adhered to a base material. Here, the reason for limiting the type and amount of synthetic resin will be explained.
（ｅ）合成樹脂の種類
銅合金粉末シートを直接焼結によって母材上に良好な合
金層を形成するには次の条件を満足する必要がある。(e) Type of synthetic resin In order to form a good alloy layer on a base material by directly sintering a copper alloy powder sheet, the following conditions must be satisfied.
（イ）常温で接着性をもちシートとしてフレキシブルで
ある。(a) It has adhesive properties at room temperature and is flexible as a sheet.
（ロ）熱分解によりガス発生が少なく、発砲変形がなく
残材の量も少ない。(b) Due to thermal decomposition, gas generation is small, there is no foaming deformation, and the amount of residual material is small.
（ハ）昇温中、母材との剥離を生ずることなく必要な形
状を保持できる。(c) The required shape can be maintained without peeling from the base material during temperature rise.
これらの条件を満足するのは、アクリル樹脂のみであっ
て、２５０°Ｃで分解し、炭化をおこすことなく、かな
りの粘着性を有している。さらに温度が上昇すると炭化
は進行するが、ガス発生による［膨れｊなどの現象は生
ぜず、６００°Ｃ以上の温度でも、母材との剥離は生じ
ない。The only resin that satisfies these conditions is acrylic resin, which decomposes at 250°C, does not cause carbonization, and has considerable adhesiveness. As the temperature rises further, carbonization progresses, but phenomena such as blistering due to gas generation do not occur, and even at temperatures of 600°C or higher, separation from the base material does not occur.
一方、熱硬化性樹脂のアクリルメラミン樹脂とアルキッ
ドメラミン樹脂、酢酸ビニール樹脂、二液硬化型（イソ
シアネート硬化型）樹脂はいずれも発砲し、ポリビニー
ルアルコールは保形性に問題がある。On the other hand, thermosetting resins such as acrylic melamine resin, alkyd melamine resin, vinyl acetate resin, and two-component curing type (isocyanate curing type) resin all foam, and polyvinyl alcohol has problems in shape retention.
（ｒ）合成樹脂の配分量 銅合金粉末シート化には次の二通りの方法がある。(r) Distribution amount of synthetic resin There are two methods for forming copper alloy powder into sheets:
（イ）アセトン、トルエン、Ｍ−Ｅ−Ｋ （メチル・エ
チル・ケトン）などの溶剤で希釈したアクリル樹脂と銅
合金粉末を混練して泥漿化した後、離型紙を被せた型枠
上に流し込み溶剤を蒸発させた後、圧延ロールに通して
シートとする。(a) After kneading acrylic resin and copper alloy powder diluted with solvents such as acetone, toluene, and M-E-K (methyl ethyl ketone) to form a slurry, pour it onto a mold covered with release paper. After evaporating the solvent, it is passed through rolling rolls to form a sheet.
（ロ）４フン化エチレン樹脂エマルジツンとアクリル樹
脂エマルジタンを１対１に混合してバインダーを作る。(b) A binder is prepared by mixing a tetrafluorinated ethylene resin emulsion and an acrylic resin emulsion at a ratio of 1:1.
これと銅合金粉末とをニーダにより十分混練した後、１
００〜１５０℃に加熱してバインダー中の水分を蒸発さ

圧延ロールに通しシートとする。ここで、バインダーと
して用いるアクリル樹脂の配合量が３％未満では、粘着

確保することがで、きす、一方１５％を越えると樹脂分
が過剰となり、気孔率に悪影響を与えると同時に、母材
との接合が不可能となることから、アクリル樹脂の配合
量を３〜１５％と定めた。After thoroughly kneading this and copper alloy powder with a kneader, 1
The water in the binder is evaporated by heating to 00 to 150°C. Further, this kneaded product is heated to 80 to 100°C and passed through a rolling roll to form a sheet. If the blending amount of the acrylic resin used as a binder is less than 3%, the adhesiveness will be insufficient and the sheet will become brittle, making it difficult to secure the necessary flexibility of the sheet. The amount of acrylic resin blended was determined to be 3 to 15% because the resin content would be excessive, adversely affecting the porosity and making it impossible to bond to the base material.
