520 3 ⊔ ‡aThe extent to which dry lubricant films could be used in future bearing systems for electrical accessory applications was determined. In Phase I, twenty each, dry film lubricated 20 millimeter bore, plain, ball and roller bearings were tested in 900 F air at 15,000 rpm with a 75 pound radial and a 25 pound axial load. All available bonded dry film lubricant coatings were applied to the bearings and tested. None were satisfactory. Two different bearing designs, which used an unconventional dry film lubrication technique, demonstrated the feasibility of operation at 15,000 rpm in 900 F air. In Phase II, roller and ball bearings were evaluated through the temperature range 70 to 1500 F at 15,000 rpm in a vacuum. The vacuum levels attained ranged between 5 x 10 to the minus 4 power mm Hg to 5 x 10 to the minus 6 power mm Hg. The initial tests in vacuum conducted on the two successful Pi bearing designs resulted in early failures. These tests showed that the dry film lubricants, which were satisfactory in air, were entirely inadequate for vacuum operation. There fore an investigation was initiated to develop new materials which would provide dry film lubrication under vacuum conditions. Over 400 compositions of dry lubricant and metal powders were fabricated using powder metallurgy techniques. Friction, wear, thermal expansion and fracture strength of these materials were determined. (Author).
