ABSTRACT:
A method of manufacturing a ceramic turbine ring rigid with an annular metallic carrier, which includes the steps of (a) moulding a ceramic member in a predetermined shape, (b) locating the ceramic member produced in step (a) and an annular cavity of a channel which defines a mould; (c) rotating the mould and moulding under centrifugal action a metallic material around the ceramic member, the rotation continuing until the metallic member has solidified; (d) demoulding the ceramic turbine ring part and its carrier produced in step (c) by disassembling the mould; and (e) machining the part produced by step (d) to produce the turbine ring.
