Description
パッドの成型性については、良好を○、使用可能を△、好ましくないを×と判定した。
走行シミュレーション摩耗試験としては、ロサンゼルス(L.A.)の市街地走行を模擬した台上試験機による試験(通称LACTシミュレーション試験)を行い、パッド推定寿命(パッド摩耗量と相関する)(km)、平均摩擦係数、ローター摩耗量(g)を調べた。
ここでは、下記の基準にて判定した。
パッド推定寿命
○:22000km以上、△:20000km以上22000km未満、×:20000km未満
平均摩擦係数
○:0.41以上、△:0.39以上0.41未満、×:0.39未満
ローター摩耗量
○:5g未満、△:5g以上10g未満、×:10g以上
また、低面圧のローター攻撃性を調べるため、相手材(鋳鉄製ディスクローター)に摩擦材を低面圧(0.5MPa)で押圧して制動させ、制動試験後における相手材の摩耗量を測定し、制動回数1000回あたりの摩耗量を換算し、下記の基準によって判断した。
低面圧のローター摩耗量
○:6μm未満、△:6μm以上10μm未満、×:10μm以上
また、被膜の緻密度については、摩擦材の摩擦面から試料を切り出し、精密機械研磨及びイオンミリングを実施したうえで走査型電子顕微鏡(SEM)を用いて断面観察を行った。緻密度については、被膜の粒界が所定の基準に対して多いものを×、少ないものを○と判定した。
また、パッドの成型性については、酸化セリウムの平均粒径が小さくなると、また酸化セリウムの配合割合が多くなると、低下する傾向にあることが分かった。
摩擦材の摩擦面に形成された被膜の緻密度については、実施例ではいずれも粒界が少なく、緻密であることが確認できた。
Claims (3)
- チタン酸アルカリ金属塩又はチタン酸アルカリ金属・第二族塩と酸化セリウムとを含有し、当該酸化セリウムの平均粒径が1μm以下である摩擦材。
- 前記酸化セリウムを1〜15体積%の範囲で含有する請求項1に記載の摩擦材。
- 前記チタン酸アルカリ金属塩又はチタン酸アルカリ金属・第二族塩を3〜20体積%の範囲で含有する請求項1または2に記載の摩擦材。
