Claims
- 1. A method of forming a metal ring structure of alternating segments of two different metal materials, which comprises providing a ring of a first metal material having teeth, plasma arc cleaning the outer surface of said ring to prepare the outer surface for plasma deposition of a second metal material, plasma spray depositing said second metal material on the outer surface of said ring to fill in the troughs between the teeth, enlarging the inner diameter of the ring by removing the material to form a ring having alternating segments of said first metal and said second metal materials.
- 2. The method of claim 1 wherein the toothed outer surface is formed by removal of segments of said first material from the outer perimeter of the ring.
- 3. The method of claim 1 wherein said first material is ferromagnetic and said second material is paramagnetic.
- 4. The method of claim 1 wherein the second metal is a superalloy.
- 5. The method of claim 1 wherein the first metal is separated from the second metal by a graded interface.
- 6. The method of claim 1 wherein the first material is first coated with an interface layer of a metal which does not form a carbide before bulk deposit of the second material, such a layer being composed of superalloy which forms carbides which weaken the ring structure.
