A gun barrel is produced by vacuum plasma spray depositing an inner layer of a refractory metal as a gun barrel liner on a mandrel, followed by deposit of successive layers of dense gun barrel jacket material to build up a structure from the inside out. The outermost layer can include attachment means for fixing the barrel into a gun mechanism.

A method is provided for forming articles from difficult to fabricate materials with precise internal dimensions. The article is first formed to approximate dimensions as a body using the material in powdered form. Plasma spray forming is proposed. The powder formed body is then brought to its final dimensions by consolidating and densifying the body about a densifying mandrel having a coefficient of expansion which is higher and outer dimensions which are slightly smaller than that of the body.

A ring is formed having alternating segments of ferromagnetic and paramagnetic materials. The ring is formed by first providing an annular ring of a high strength magnetic steel. Teeth are formed on the outer surface of the ring by forming troughs of the ferromagnetic material. Low pressure plasma deposition is used to fill in the troughs with a high strength paramagnetic material. The excess steel and excess plasma deposited material is removed to leave the finished ring of alternating segments of ferromagnetic and paramagnetic material.
