The lubricity of graphite flake inclusions in sintered polyimides affected by chemical reactions at high temperatures Original Research Article

The internal lubrication of 15 vol% graphite flakes added to polyimide was investigated during sliding at 50–200 N normal loads, 0.3 m/s and 23–260 °C, showing that chemical reactions in the polyimide bulk have an important effect on the sliding efficienc
