Abstract
The high temperature (25°C to 538°C) traction characteristics of graphite lubricants containing additives of silver, phosphate glass, and zinc orthophosphate were evaluated in a specially designed ball-on-disk traction device. Bearing quality balls of hot-pressed silicon nitride burnished with the graphite lubricant were loaded against lubricated disks of hot-pressed silicon nitride. Characteristic behavior of the measured tractions was similar in nature to that of liquid lubricants, however, traction force magnitudes were often much higher. Traction coefficients ranged from us low us 0.07 to as high as 0.66. Based on the data collected, an empirical solid lubricant traction model was constructed and applied to an advanced bearing analysis code.
