Description
前記酸化皮膜が前記軸受部品を構成する元素である鉄が前記固体潤滑膜中に拡散しないバリア層を形成して成り,前記酸化皮膜は,オゾン酸化処理によって前記軸受部品の前記表面に形成されて前記酸化皮膜の厚さが0.01〜2μmになっていることを特徴とする固体潤滑軸受に関する。
オゾン発生器で得られた酸素と0.2%オゾンの混合ガス中で種々の時間にわたって曝したSUS440C製のローラと,SUJ2製のローラに,また,SUS440C製の円板に固体潤滑膜を,0.6μmの厚さに被覆した。酸化皮膜の形成時における軸受部品のローラの温度は,室温としたが,処理時間を短縮する意味で,温度を上げて処理しても良い。ローラ表面への固体潤滑膜の形成には通常行われている方法を採用しており,固体潤滑膜の銀はイオンプレーテング法であり,また,硫化物はスパッタ法である。固体潤滑膜を被覆したローラを軸受に組み込んで,真空中での寿命を測定した。測定条件は,真空度0.02Pa,転がり速度8m/分,荷重1.5N,面圧114N・m/mm2 ,及び温度25℃である。酸化皮膜の厚さは,ESCA(Electron Spectroscopy for Chemical
Analysis, X線光電子分光)による深さ方向分析とローラの断面をEPMA(Electron
Probe Micro-analyzer, X線マイクロアナライザ)で測定する方法を併用して求めた。酸化皮膜が0.01μm以下では,その厚さを正確に測定することができなかったが,酸化皮膜の存在は確認できた。固体潤滑膜中の鉄元素の測定は,XPS(X-ray PhotoelectronSpectroscopy, X線光電子分光)で行った。実施例1,実施例2及び実施例3についての結果を,表1に示す。
