Polyimide Film Wear - Effect of Temperature and Atmosphere.

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
