Friction and Wear of Poly(Amide-Imide), Polyimide, and Pyrrone Polymers at 260 deg C (500 deg F) in Dry Air.

Abstract

A pin-on-disk sliding friction apparatus was used to determine the friction and wear of (1) a poly(amide-imide), (2) a polyimide, and (3) a pyrrone in dry air at 260C (500F). Low wear was obtained with a pyrrone, intermediate wear with a polyimide, and very high wear with a poly(amide-imide). All three polymers exhibited low (<0. 20) coefficients of friction. The poly(amide-imide) exhibited thermal degradation at 260C (500F). Experiments were conducted using a hemispherically tipped rider (pure polymer) sliding on a rotating steel disk. Other conditions included a sliding speed of 10 m/min (390 in. /min), a 1. 5-kg load, and a mineral oil lubricant.
