<軸受試験条件1>
・試験軸受:深溝型軸受(外径39mm、内径17mm)
・軸受材料:軸受鋼(SUJ2)
・ハウジング:アルミニウム合金
・試験ラジアル荷重:3577N
・内輪回転数:3900min−1
・雰囲気:CTVフルード、強制供給潤滑
・試験温度:100℃
・時間:48時間
・評価項目:ハウジングの摩耗量
本試験では、焼成膜に含まれる摩擦摩耗調整剤(酸化アンチモン)の影響を検討するために、表2に示す組成の焼成膜を形成した試験軸受を用い、上記の条件1にて評価した。また、二硫化モリブデンの原料粉末の平均粒径は3μm、酸化アンチモンの原料粉末の平均粒径は1μmとした。尚、下地処理としてリン酸マンガンを用いた化成処理を施し、有機バインダーとしてポリアミドイミド、硬化剤としてエポキシを使用した。また,焼成膜の膜厚は15μmとした。結果を表2に、(固体潤滑剤/摩擦摩耗調整剤)比と、ハウジング摩耗量との関係で示した。ハウジングの摩耗量は比較例2を1としたときの重量比で表すが、この値が小さいということはクリープ現象によるハウジングの摩耗が少ないことを示す。
・試験軸受:深溝型軸受(外径53mm、内径30mm、厚さ13mm)
