45鋼化學熱處理表面與極壓抗磨添加劑的協同作用

Synergistic Effects between the Chemical Heat Treatemnt Surfaces of 1045 Steel and Extreme Pressure-Antiwear Additives

  • 摘要: 利用球一盤摩擦磨損試驗機系統地研究了45#鋼氧氮共滲、滲氮及滲硫3種化學熱處理表面與硫化烯烴及磷酸三甲酚醋2種極壓抗磨添加劑的協同作用效果,并利用X射線光電子能譜儀和俄歇電子能譜儀分析了各摩擦表面潤滑膜的結構及成分,進而討論了它們的協同作用機理.研究結果表明,在減摩、抗磨及提高承載能力方面這種協同作用效果十分顯著。

     

    Abstract: The synergistic effects between three kinds of chemical heat treatment surfaces of 1045 steel,including oxy-nitrided, nitrided and sulfurized surfaces,and two kinds of extreme pressure (EP)-antiwear(AW) additives, sulfurized olefin and tricresyl phosphate, were studied systematically on a ball-on-disc testing machine. The composition of lubricating films on disc wear surfaces was analysed using X-ray photoelectron spectroscopy and Auger electron spectroscopy methods.The mechanism of the synegistic effects was discussed. It was found that exeellent synergistic effects on increasing load carrying capacity and reducing friction and wear could be obtained.
