Abstract
Description
Cu:50%以上
Cuは、高い熱伝導性を有する元素であり、本発明では焼結摩擦材料の素地をなすものである。このCu主体の焼結体を得るためには、Cuを50%以上含有させる必要がある。Cuの含有量の上限は、添加成分との兼ね合いで定めればよく、特に限定しないが、67%以下とするのが好ましい。
Feは、鋼製のディスクに対して、ともがね効果が最も大きい元素である。この効果を得るためにはFeの含有量を7.5%以上とする必要がある。Fe含有量の上限は特に定めないが、Fe含有量が多すぎる場合、焼結温度によっては耐摩耗性が低下する場合がある。このため、Feの含有量は、36%以下にするのが好ましい。
黒鉛:5~15%
黒鉛は、ディスクとライニングとの間に介在することで、これらの凝着を抑制し、摩擦係数の安定化および耐摩耗性の向上に有用である。この効果は、その含有量が5%未満では十分に発揮されない。一方で、その含有量が15%を上回ると、焼結体の材料強度が低下する。
二硫化モリブデン(MoS2)は、黒鉛と同様、摩擦係数の安定化および耐摩耗性の向上に有用であるとともに、いわゆる「鳴き」の防止効果を有し、更に、高荷重時には潤滑性を与えるという効果も有している。この効果は、0.3%未満では発揮されず、7%を超えると、焼結体の材料強度が著しく低下し、耐摩耗性が損なわれる。
シリカ(SiO2)は、いわゆる「掘り起こし効果」によって相手材であるディスク表面に生じた酸化皮膜を除去して、ディスクとライニングと間で生じるFe同士の凝着を安定的に発生させて、摩擦力を確保するのに有効である。しかしながら、0.5%未満では、掘り起こし効果が生じず、一方、10%を上回るとディスク表面を荒損させる。
本発明の焼結摩擦材料は、一般的な製造方法、例えば、Cu粉にFe粉、各種添加物などを混合し、成形した後、焼結することによって製造することができる。また、原料として用いられるCu粉末に、アトマイズ等による粉末作成時に、あらかじめFeを含有させた原料粉末を用いても良い。
