Thereafter, the lining 3 is applied to the noble metal layer 2a on the back metal surface 1a side. At this stage, the base material 12 of the sliding member is obtained.
- the base material 12 of the sliding member is connected to the cathode, and the Bi-based overlay layer 10 is deposited by electroplating by immersing the entire surface in an electroplating solution. Since Bi in the Bi-based overlay layer 10 is baser than the metal in the noble metal layer 2, substitution / precipitation of the noble metal layer 2b and Bi (alloy) does not occur. That is, the noble metal layer 2b is lightly etched by the plating solution, but Bi (alloy) is not electrodeposited. The noble metal layer 2a is not involved in preventing corrosion of the back surface of the back metal, but is present between the lining 3 and the back surface (1a) and has an effect of improving the adhesion between the lining 3 and the back metal 1.
- Bi electroplating Preferred conditions for Bi electroplating are as follows. Alkanesulfonic acid 70g / L Bi ion 10g / L pH about 0 Temperature 25 ° C Current density 2A / dm 2 20 minutes

That is, Bi (alloy) is not electrodeposited on the noble metal layer 2.
- Elements such as Al, Ti, Cr, and Ni are base metals than Bi in the Bi-based overlay layer, and the surface changes to Al 2 O 3 , TiO 2 , Cr 2 O 3 , NiO, and the like to be passivated. Therefore, Bi (alloy) is not electrodeposited on the surface, and these base metals can be used in place of the noble metal layer 2.
- These base metal layers are formed on the desired surface by vapor deposition of Al, Ti, etc., vapor deposition of Cr, Ni, or the like, or electroplating, and then a passivation treatment is performed.

- Comparative example A SPCC steel plate having a thickness of 1.3 mm is used as the backing metal 1 (Fig. 1), and a Cu alloy layer having a thickness of 0.2 mm is used as the lining 3 without depositing the noble metal layers 2a and 2b.
- Composition: Cu-5% Sn was bonded to the surface to be the surface side (1a) of the back metal 1.
- the base material 12 prepared as described above was connected to the cathode, immersed in a Bi electroplating bath having the above composition, and the Bi-based overlay layer 10 was plated to a thickness of 7 ⁇ m under the current density conditions. After plating, roughening of the skin was observed when the back side (1b) surface was observed. The roughness Rz on the back metal back surface (1b) side was 25 ⁇ m.
- Example 1 In FIG. 1, a 1.3 mm thick SPCC steel plate was used as the backing metal 1, and a 0.2 mm thick Cu alloy (composition: Cu-5% Sn) was used as the lining 3.
- Cu is deposited on both sides of the back metal 1 as a noble metal layer 2a, 2b by electroplating to a thickness of 2 ⁇ m under the condition of a cyan bath and a current density of 2 A / dm 2 .

- the base material 12 prepared as described above was connected to the cathode, immersed in the entire surface of the Bi electroplating bath, and the Bi-based overlay layer 10 was plated to a thickness of 7 ⁇ m under the current density conditions. After plating, when the surface of the back metal back side 1b was observed, it was almost the same as the electroplated surface, and no rough skin or Bi electrodeposition was observed.
- Example 2 In FIG. 2, the same back metal 1, lining 3, noble metal layer 2 and Bi overlay layer 10 as in FIG. 1 were deposited by electroplating. However, the noble metal layer 2 was deposited only on the back surface 1 b of the back metal 1. After plating, when the surface of the noble metal layer 2b on the back side of the back metal was observed, the surface was almost the same as the electroplated surface, and no rough skin or Bi electrodeposition was observed.
- Example 3 In FIG. 2, the same back metal 1 and lining 3 as in FIG. 1 were formed. Thereafter, the Cr and Ni layers 2 were deposited on different test materials by electroplating, and when left at room temperature, the surface 2 ′ was passivated to become Cr 2 O 3 and NiO. Thereafter, the Bi-based overlay layer 10 was deposited by electroplating. After plating the Bi-based overlay layer 10, the surface of the Cr 2 O 3 layer and the NiO layer 2 ′ on the back side of the back metal was observed. Was not recognized.
- Example 4 In the layer structure shown in FIG. 1, the same back metal 1, lining 3 and Bi-based overlay layer 10 as in FIG. 1 were formed. However, instead of the noble metal layers 2a and 2b, the Cr or Ni layer 2 was deposited on the both sides of the back metal 1 by electroplating on separate specimens, and the Cr or Ni layer 2b on the back metal side was left at room temperature. However, the surface was passivated to become Cr 2 O 3 and NiO. On the other hand, the Cr or Ni layer 2a on the lining side was reduced in the atmosphere when the lining 3 was formed by sintering, so Cr 2 O 3 was reduced to Cr and NiO was reduced to Ni.
- Example 5 In FIG. 3, the same back metal 1, lining 3, epoxy resin layer 4, and Bi overlay layer 10 as in FIG. 1 were formed.
- the epoxy resin film 4 was baked at 100 ° C. after coating to a thickness of 3 ⁇ m. After the formation of the 10 Bi-based overlay layers, the surface of the epoxy resin layer 4 was observed. As a result, it was almost the same as that after the application, and rough skin and Bi electrodeposition were not observed.
- the present invention can prevent the deterioration of the performance of the back metal plate, which was unavoidable in the past when manufacturing a plain bearing provided with a Bi-based overlay layer, it greatly contributes to the industry.

例えば、特許文献2:特開2004-308883号公報によると、上記した積層構造の摺動部材が提案されており、すべり軸受合金としては、Cu又はAl系合金が使用され、またオーバレイ層としては、(202)面の配向指数が30%以上であり、かつ他の面と比較して最大値を示すようにPR電解法により配向制御したBi又はBiめっき合金が使用されている。
ここで、Pb系オーバレイ層を電気めっきにて被着する場合、裏金鋼板は電気良導体であるにもかかわらずPb系オーバレイ層が置換・析出しない理由は、PbとFeとの電位差が少ないからである。
解・析出して脆い皮膜を形成する。裏金背面にはこのような過程で一旦はBiめっき皮膜が形成されるが、そのBiめっき皮膜やFeイオンの再析出皮膜は裏金から簡単に脱落してしまうために、最終的に裏金鋼板背面にはBi系合金が存在しておらず、精密に観察すると、裏金背面は全面腐食により肌荒れ(微小凹凸)を呈していることが分かった。裏金鋼板背面はエンジン軸受の場合はコンロッドの大端部もしくは小端部と衝突し、かつ摺動するため、上記のように裏金鋼板背面に腐食による肌荒れ(微小凹凸)があると、エンジン軸受などの疲労破壊などを起こすおそれがある。

(7)貴金属又は卑金属からなる第2の保護層を裏金鋼板とすべり軸受合金層の間に有することを特徴とする(6)記載の摺動部材。
以下、本発明を詳しく説明する。
Cuの標準電極電位(標準水素電極をOVとする。以下同じ)は:Cu=+0.337Vである。ところで、Bi=Bi3++3e-の反応が示す標準電極電位(25℃)は+0.22Vであるため、CuはBiより電気化学的に貴である。なお、Cu系すべり軸受合金の標準電極電位は上記の値を基準として変動する。
Al系すべり軸受合金の標準電極電位はAl=Al3++3e-の反応の-1.66Vを基準とする。したがって、BiはAlよりも電気化学的に貴である。
本発明においては、裏金鋼板の表面にすべり軸受合金層を圧延又は焼結により接合し、その後すべり軸受合金層上にBi系オーバレイ層を電気めっきにより被着する公知の工程を順次行う。
本発明は、上記工程の中で、裏金鋼板の少なくとも背面に、Bi系オーバレイ層の電気めっきより前の段階で、Biよりも電気化学的に貴な金属(即ち「貴金属」)、Biよりも卑な金属であって不働態化する金属(即ち「卑金属」)、あるいは樹脂皮膜のいずれか1種よりなる保護層を形成することを特徴とする。
の電気めっきを行う。第1及び第2の保護層は同一物質であると、両層を同時に形成することができる(上記(3)の方法)。なお、第2の保護層が卑金属であるとその表面に存在する不働態膜がライニングの下に存在するために、Bi系オーバレイ層を電気めっきする際に電極を摺動部材母材に取付ける方法が複雑になる。即ち、摺動部材を両側から鋏ではさみ付ける方式での電極取り付けでは通電不良となるおそれがある。したがって、第2の保護層表面の不働態層をBi系オーバレイ層電気めっき前に、酸洗いなどにより除去することが好ましい。なお、第2の保護層がNi,Crからなり、ライニングが銅合金であると、不働態層は還元性焼結雰囲気により還元され、消失する。

これらの酸化物は電気不良導体であるので、裏金とは反対側面2bにおいてBi(合金)との置換・析出は起こらないが、その中でも上記した酸化物はFe-Crなどのステンレス鋼や、Al系材料などの不働態皮膜成分としても知られており、安定な保護効果をもたらす。
比較例
裏金1(図1)として厚さが1.3mmのSPCC鋼板を使用し、貴金属層2a,2bを被着せずに、ライニング3として厚さが0.2mmのCu合金層(組成:Cu-5%Sn
)を、裏金1の表面側(1a)となる面に接合した。その後、上記のようにして作成した母材12を陰極に接続し、上記組成のBi電気めっき浴に全面浸漬し、上記電流密度条件でBi系オーバレイ層10を7μmの厚さにめっきした。めっき後、裏金背面側(1b)の面を観察したところ肌荒れが認められた。この裏金背面(1b)側の粗さRzは25μmであった。
図1において、裏金1として厚さが1.3mmのSPCC鋼板を使用し、ライニング3として厚さが0.2mmのCu合金(組成:Cu-5%Sn)を使用した。まず、裏金1の両側に貴金属層2a、2bとしてCuをシアン浴、電流密度2A/dm2の条件で2μmの厚さに電気めっきにより被着した後、水洗・乾燥を行い次に裏金1の表面側(1b)となる面にライニング3を接合した。その後、上記のようにして作成した母材12を陰極に接続し、上記Bi電気めっき浴に全面浸漬し、上記電流密度条件でBi系オーバレイ層10を7μmの厚さにめっきした。めっき後、裏金背面側1bの面を観察したところ、電気めっき状態の表面とほとんど変わらず、肌荒れやBiの電析は認められなかった。
図2において、図1と同じ裏金1、ライニング3及び貴金属層2及びBi系オーバレイ層10を電気めっきにより被着した。但し、貴金属層2は裏金1の背面1bにのみ被着した。めっき後、裏金背面側の貴金属層2bの表面を観察したところ、電気めっき状態の表面とほとんど変わらず、肌荒れやBiの電析は認められなかった。
図2において、図1と同じ裏金1、ライニング3を形成した。その後、別々の供試材に電気めっきによりCr及びNi層2を被着し、室温に放置したところ表面2´が不働態化してCr2O3とNiOなった。その後、Bi系オーバレイ層10を電気めっきにより被着した。Bi系オーバレイ層10のめっき後、裏金背面側のCr2O3層及びNiO層2´の表面を観察したところ、電気めっきに続く室温放置状態の表面とほとんど変わらず、肌荒れやBiの電析は認められなかった。
図1に示す層構造において、図1と同じ裏金1、ライニング3及びBi系オーバレイ層10を形成した。但し、貴金属層2a,2bの代わりに、別々の供試材にCr又はNi層2を裏金1の両側に(電気めっき)により被着し、裏金側のCr又はNi層2bは室温に放置したところ、その表面が不働態化してCr2O3とNiOなった。一方、ライニング側のCr又はNi層2aはライニング3を焼結により形成する際の雰囲気が還元性であったので、Cr2O3がCrに、NiOがNiにそれぞれ還元された。Bi系オーバレイ層10のめっき後、裏金背面側のCr2O3層及びNiO層2b´の表面を観察したところ、電気めっきに続く室温放置状態の表面とほとんど変わらず、肌荒れやBiの電析は認められなかった。
図3において、図1と同じ裏金1、ライニング3及びエポキシ樹脂層4及びBi系オーバレイ層10を形成した。エポキシ樹脂皮膜4は塗布により厚さ3μmに塗布後、100℃で焼成した。Bi系オーバレイ層10層形成後、エポキシ樹脂層4の表面を観察したところ、塗布後の状態とほとんど変わらず、肌荒れやBiの電析は認められなかった。
