Abstract : The tribological properties of seven polyimide films applied to 440C high-temperature stainless steel substrates were studied at 25 deg C (room temperature) on a pin-on-disk friction and wear apparatus. The polyimides fell into two groups according to friction and wear properties. The polyimides in group I had slightly lower friction but much higher wear than those in group II. The wear rate for group II polyimides was about an order of magnitude lower than that for group I polyimides. jg p4
