Abstract
An improved method of forming components by hot isostatic pressing (HIP) involves making a can for the HIP process from a ceramic mould, reducing the need for welding & machining in the production of the can.
Claims22
A method of forming a component from metal powder, comprising the steps of:
- a. providing a ceramic mould using a lost wax process;
- b. casting liquid metal in the ceramic mould to form a can;
- c. forming one or more holes in the can;
- d. filling the can through the hole or holes with the metal powder;
- e. settling the metal powder in the can, evacuating the can of gas and sealing the can;
- and
- f. subjecting the can and contained powder to a hot isostatic pressing environment to fuse the metal powder into a solid component.
4 more elements
A can for use in a hot isostatic pressing process for the formation of a metal component from powder of the metal,
- whereby the can has either:
- a no weld seams between surfaces of the can that contact the powder during said hot isostatic pressing process, or
- b. weld seams only around a single lid of the can, which lid closes a hole left by the moulding process forming the can, and wherein:
- the can has a wall thickness of between 1 and 5 mm.
