Abstract
There is disclosed a rotor housing for a rotary piston engine which is designed particularly for high output power wherein the rotor housing inner wall surface is required to possess heat and wear resistant properties, improved affinity to lubricant oil, resistance to uneven wear which may cause chatter marks and scratches, oil retaining property, and less harmfulness to the apex seal. The rotor housing is formed at the inner wall surface with a porous Cr-Mo plating containing 0.50 to 0.90% in weight of Mo.
