Abstract:

Friction and wear experiments conducted on polyimide films bonded to 440C stainless steel disks indicated that a wear transition from high wear to low wear accompanied a friction transition from high friction to low friction. In dry argon or dry air 20 ppm H2O, the transition was found to occur at 40 deg or - 10 deg C when H2O was present in air 10 000 ppm H2O, the transition was found to be elevated to a temperature between 100 deg and 200 deg C. Wear rate calculations made at 25 deg, 100 deg, and 200 deg C indicated that film wear was relatively constant for particular experimental conditions however, the rate was strongly dependent on temperature and atmosphere. jg p2
