Abstract
A method of making a turbine nozzle comprises the steps of forming a destructible mold in the configuration of a fluid passage through said nozzle, coating the mold with a succession of layers of different materials, removing the mold so as to form a hollow vane segment, assembling a plurality of hollow vane segments in a circumferential array, and bonding the vane segments to one another to form the nozzle.
