Abstract

PURPOSE: To increase a wear and heat resistance and heighten a lubricating ability in rotary engine, by slidably contacting an apex seal, in which a layer of Fe-C-N system compound is provided on surfaces of chilled layer of the base unit, to within a rotor housing processed chrome plating.
CONSTITUTION: In inner circumferential surfaces of a rotor housing 3, is constructed a chrome plated layer. An apex seal 1 is made by constructing a chilled layer 7 in the portion of a base unit 6, made of cast iron, that is, in the sliding surface with the rotor housing 3, and a compound layer 8 of Fe-C-N system, processed a soft nitration treatment, in the topmost surface of the chilled layer 7.
