RADIOMETRIC STUDY OF THE WEAR CHARACTERISTICS OF DRY FILM LUBRICANTS.

Abstract

The wear life of dry film lubricants as related to percent coating loss was studied by use of a radioactive tracer technique. The contribution to the total wear life by various combinations of the three basic ingredients--molybdenum disulfide, antimony trioxide, and dibasic lead phosphite was studied. Tests were run on a Falex Lubricant Tester to determine the percent coating loss of different formulations for various time periods. Percent coating loss was determined from counting rates of the pins, coated with tagged formulations, before and after testing. The test results indicated a linear relationship between percent coating loss and length of test. It was found that a prediction of the relative wear lives of different formulations could be made on the basis of the percent coating loss results, determined after one hour of testing.
