FORMING A ROTARY PART

A method of forming a rotary part is disclosed. The method comprises (a) rotating a mandrel about an axis, (b) delivering a metal feed onto the surface of the mandrel and (c) exposing the particles at the surface to a high energy discharge so that the particles melt together to form a surface layer...

Zusammenfassung:	A method of forming a rotary part is disclosed. The method comprises (a) rotating a mandrel about an axis, (b) delivering a metal feed onto the surface of the mandrel and (c) exposing the particles at the surface to a high energy discharge so that the particles melt together to form a surface layer of metal. The method also comprises repeating steps (a) to (c) by subsequently delivering the metal feed onto the formed surface layer to form the rotary part radially from the mandrel to an outer perimeter with a desired size and shape. Also disclosed are rotary parts formed by the method and an apparatus for forming a rotary part in accordance with the method.
