Abstract
PURPOSE:To improve toughness of base metal itself and to enhance wear resistance of the sliding surface of an apex seal by forming a vanadium diffusion layer comprising mainly vanadium carbonate, on the sliding surface of the apex seal sliding in contact with the inner periphery surface of a rotary housing. CONSTITUTION:In an apex seal A sliding on the inner periphery surface of a rotor housing, mounted on the top of a rotor of a rotary piston engine, the base metal (a1) thereof is made of alloy tool steel material. On a slaiding surface (a2) sliding in contact with the inner periphery surface of the rotor housing of the apex seal A, a vanadium diffusion layer (a3) comprising mainly vanadium carbonate, having a thickness of about 5 to 50mum, wherein VC of 90wt.% or more and FeV, FeC<delta-VFe of trace quantity are deposited. Therefore, it is possible to improve toughness of the base metal (a1) itself to prevent breakage and to enhance wear resistance of the sliding surface (a2).
