A representative solid film lubricant for each specification, MIL-L-8937ASG, MIL-L-46009MR and MIL-L-46010MR, was evaluated on the Falex Wear Tester under various combinations of test load and temperature. Based on a statistical analysis of the data the following conclusions can be made 1 The effect of temperature on wear life depends on both solid film lubricant type and test load. 2 The wear life of heat cured solid film lubricants is decreased by increased temperature at the lower test loads. The wear life of air cured solid film lubricants is affected very little by temperature. 3 The effect of load on wear life is dependent on lubricant type but not on temperature. 4 For heat cured solid film lubricants a constant short wear life under high loads occurs followed by a rapid increase in wear life with decreasing load and finally a leveling off of wear life with further decreasing of the load. 5 For the air cured solid film lubricant there is a constant short wear life over an extended load range followed by a rapid increase in wear life with a further decrease in load. Over the load range used there is no apparent leveling off of wear life under the low load condition. Author
