A factorial experiment was designed for evaluating the performance of a ceramic bonded solid film lubricant consisting of PbS/B2O3 in a 6:1 weight ratio. The effects of three factors, each at two levels were studied. These were bearing load, sliding speed, and rub block temperature. An analysis of variance of the test results was made. At 200 rpm, wear life increased with an increase in temperature between 700 and 1000 F for both load levels of 100 and 200 lb. At 600 rpm, however, wear life decreased with increasing temperature between 700 and 1000 F for both load levels. All results were obtained from runs made in air.

Organic Resin

A new thermally stable organic resin is described. Results are presented for the development of polybenzimidazole (PBI) resin-bonded solid-film lubricants. These solid-film lubricants are composed of molybdenum disulfide, antimony trioxide, and the PBI resins. Steps followed for mixing, applying, and curing these films are presented. The test equipment and procedures used to test the film formulations are described. Wear-life comparisons to conventional commercially available resin-bonded films qualified under MIL-L-8937 are presented.
