摘要: Characterization of the coefficient friction and wear rate 440C stainless steel is needed to understand effects frictional heating in bearings High Pressure Oxygen Turbopump Space Shuttle Main Engine. The have been measured over a range temperature varying from liquid oxygen (−184°C) 750°C. normal load has also varied resulting variation Hertzian stress 0.915 3.660 GPa while surface velocity 0.5 2.0 m/s.
