Abstract
Description
図1は、一実施形態に係る摺動部材を例示する図である。ここでは、摺動部材として半割軸受を図示している。この摺動部材は、一実施形態に係る摺動部材用合金で形成された層を含む。この摺動部材用合金は、Cu系合金(銅合金)である。このCu系合金は、いわゆるCu−Sn−Ni−Bi−Ag系の合金であり、(A)Sn、(B)Ni、(C)Bi、及び(D)Agを含む。なお、残部はCu及び不可逆不純物からなる。不可避不純物は、例えば、Al、Fe、Sn、Mg、Ni、Ti、B、Pb、及びCrの少なくとも1種を含む。不可逆不純物は、例えば、精錬又はスクラップにおいて混入する。不可避不純物の含有量は、一例として、総量で1.0質量%以下である。
(A)Sn:5〜10質量%。5〜8.5質量%であることがより好ましい。
(B)Ni:2〜7質量%。3〜6質量%であることがより好ましい。
(C)Bi:1〜5質量%。2〜4.5質量%であることがより好ましい。
(D)Ag:0〜0.3質量%。0.01〜0,2質量%であることがより好ましい。
なおここで、5〜10質量%とは5質量%以上、10質量%以下の意味である。
図5は、一実施形態に係る摺動部材用合金を用いた摺動部材の製造方法を例示するフローチャートである。ステップS1において、銅合金の原料粉末が準備される。この例においては、Cu−Sn−N−B−Ag合金粉が用いられる。なお、これに加えて、又は代えて、単体金属粉を混合したもの(混合粉)が用いられてもよい。ステップS2において、原料粉末が裏金上に散布される。ステップS3において、一次焼結が行われる。一次焼結の条件は、水素還元雰囲気中で、温度850℃、保持時間10分である。一次焼結後、圧延(ステップS4)された後、二次焼結が行われる(ステップS5)。二次焼結の条件は、一次焼結と同一である。二次焼結後のワークは、帯の形状を有しており、例えばロールに巻き取られて次の工程に供される。ステップS6において、合金材が所望の形状に加工され、摺動部材が得られる。
本願の発明者らは、種々の条件で摺動部材の試験片(サンプル)を作製し、これらの試験片について耐摩耗性及び摩擦係数を評価した。まず、作製した試験片に用いた合金の組成及び断面組織におけるNi−Sn相(Ni−Sn金属間化合物相)の面積率は表4のとおりである。なお、断面組織におけるNi−Sn相の面積率は以下の方法により計測した。まず、断面をSEM−EDX(日本電子社製JSM−6610A)によって300倍の光学倍率で撮影し、観察画像の画像データを得た。そして、この画像データを画像解析装置(ニレコ社製LUZEX_AP)に入力し、観察画像に存在する相の面積を計測した。図2の例に示すように、摺動部材用合金の断面組織において、マトリックスに対して相対的に色の薄い層がNi−Sn相である。
試験形態:ブロックオンリング
荷重: 90N
回転数: 0.5m/s
時間: 30分
油種: パラフィン油
油温: 室温
