Beschreibung
Zusammenfassung:	A method of making an integrally bladed disc for a gas turbine engine, the disc having at least one blade the radially outermost surface of which is coated with a material harder than that of the blade, the method comprising the steps of: providing a forged disk blank of a first material; friction surfacing at least part of the circumference of the blank with a second material harder than the first material; and machining the blank so as to provide an integrally balded disc wherein the radially outermost surface of at least one blade is coated with said second material.
