Abstract : The report is concerned with the wear rates of three lubricant compact materials, selected as representative of a new class of engineering compounds. The compacts were subjected to various combinations of loads and sliding velocities, from 200 to 1,600 psi and from 1.50 to 9.60 ft/sec. Weight loss data as a function of time are presented, showing that wear rate does not change significantly with time. Repeatability, effects of operational eccentricity, and temperature are also discussed. A statistical interpretation of the data is presented, including the concept of bands of wear rate values instead of simple arithmetic averages. Using the statistically acceptable spread of wear rate values, equations relating wear rate, load, and sliding velocity were formulated. (Author)
