<p>A rotor for rotary piston engines having flanks coated with coatings of a modified fluorine resin. The modified fluorine resin is prepared with a fluorine resin, such as tetrafluoroethylene resin, and a binder resin, such as epoxy resin. The coating layer is formed by applying the modified resin to the flank surface of the rotor and drying it at a low temperature to have the resin adhered to the flanks. The coating is heat-resistant and has an anti-peel-off property. The coating is softened during engine operation so that it can catch deposits of unburnt residual substances. The rotor is therefore effective to prevent carbon lock.</p> |
