Description
Cuは、Sn、Pと固溶体を形成し、このCu−Sn−P固溶体は相手軸よりも軟らかく、相手軸とのなじみ性を向上させ、もって軸受の耐摩耗性向上に寄与する。Cuの含有量が10質量%未満では、所望の効果が得られず、一方その含有量が55質量%を超えると軸受強度が不足するようになり高負荷条件での軸受摩耗が大きくなるので好ましくない。
Snは、Cu、Pと素地の固溶体を形成し、軸受の強度を向上させ、もって軸受の耐摩耗性向上に寄与する。Snの含有量が0.5質量%未満では所望の効果が得られず、一方その含有量が7質量%をこえても強度向上に効果がなく、かえって寸法精度が低下するので好ましくない。
Znは、Cu、Snと素地の固溶体を形成し、軸受の耐食性、なじみ性及び強度を向上させる作用がある。Znの含有量が4質量%を超えても所望の効果向上がないので、添加する場合は4質量%以下とするのが好ましい。
Pは、Cu−P合金粉末で添加され、焼結時液相を発生させ、焼結を進めると共にCu、Sn素地の固溶を形成し、耐摩耗性を向上させる作用がある。Pの含有量が0.6質量%を超えても所望の効果向上がなく、かえって焼結時の変形が大きくなるので好ましくないので、添加する場合は0.6質量%以下とするのが好ましい。
Cは、軸受合金の素地中に遊離黒鉛として分散分布することで、軸受に優れた潤滑性を付与し、もって耐摩耗性向上および摩擦係数の低減に寄与する。Cの含有量が0.5質量%未満では耐摩耗性の向上効果が得られず、その含有量が4.5質量%を超えると強度が著しく低下するので好ましくない。
気孔は素地に分散し、軸受が受ける強い摩擦を緩和し、軸受けの摩耗を抑制する効果があるが、気孔率が16%未満ではその効果が十分でなくなる。一方、気孔率が25%を超えると強度が著しく低下するので好ましくない。
原料粉末に用いる黒鉛粉末としては、鱗状黒鉛粉末と鱗片状黒鉛粉末のうちの少なくとも1種を用いることができる。鱗状黒鉛粉末と鱗片状黒鉛粉末は、軸受合金の素地中に遊離黒鉛として分散分布することで軸受に優れた潤滑性を付与し、もって耐摩耗性向上及び摩擦係数の低減に寄与する。鱗状黒鉛粉末又は鱗片状黒鉛粉末の平均粒径が10μm未満では、焼結時に原料粉末中の鉄粉と反応し鉄合金相の硬度を上げるとともに遊離黒鉛の面積率が低下するためその効果が得られず、一方、平均粒径が100μmを超えると強度が著しく低下するようになるので好ましくない。
