Abstract

A method of manufacturing a radial flow turbine rotor is disclosed, which comprises the steps of injection molding a rotor body including a conical shaft and a plurality of blades formed on the periphery of the shaft and at an angle to the axis of the shaft from a ceramic material using a mold having parting lines corresponding to blade edges such that projections are formed on the blade edges, sintering the molding thus obtained, and grinding the edge surfaces of the blades facing a casing. The blades are thus provided with projections on their inlet and outlet edges which face a fluid passage.
