An Investigation of Scuffing Conducted on the AFAPL Disk Tester

Abstract

The report presents the results of scuffing studies conducted on the AFAPL disk tester developed earlier. A total of 90 tests were conducted using AMS 6260 CEVM steel disks and a MIL-L-7808G lubricant at various combinations of sliding and sum velocities, at two lubricant jet temperatures, with two methods of driving the test disks, and in air and inert environments. The load-carrying capacity is seen to decrease with increasing sliding velocity, increase with increasing sum velocity, decrease with increasing lubricant jet temperature, decrease with belted as against unbelted drive, and decrease in the presence of an inert environment. The variations of the critical temperature, the minimum lubricant film thickness ratio at failure, and the friction coefficient at failure with respect to the variables investigated are presented and discussed.
