Abstract
Abstract A method for forming fiber reinforced titanium alloy composite is taught. The composite is formed with an inner and outer high density skin of titanium base alloy prepared by RF plasma spray depositing larger size particles of the alloy. The first skin is formed on a substrate, the fiber reinforcement is applied over the inner portion of the first skin and then a second skin is RF plasma deposited over the reinforcement and outer or edge portions of the first skin to seal the contents of the composite. The composite is then hot isostatic pressed to densify its contents without being enclosed in any auxilliary container such as the conventional HIPing container.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
130 words
The method of forming a relatively high density structure including an enclosing envelope of low pressure plasma deposited titanium base metal which comprises RF plasma spray depositing at low pressure a first low porosity outer layer of said metal as a first element of said envelope, superposing on said first outer layer a sub-compact to be consolidated to high density, low pressure RF plasma spray depositing a second low porosity outer layer of said metal as a second element of said envelope over said sub-compact to form a compact which includes a sealed envelope of titanium based metal plasma deposited about said sub-compact, and consolidating the compact so formed at high pressure and high temperature to a relatively high density structure by direct application of fluid pressure to said envelope.
Claim 2
Independent Claim
130 words
The method of forming a relatively high density structure including an enclosing envelope of low pressure plasma deposited titanium base metal which comprises RF plasma spray depositing at low pressure a first low porosity outer layer of said metal as a first element of said envelope, superposing on said first outer layer a sub-compact to be consolidated to high density, low pressure RF plasma spray depositing a second low porosity outer layer of said metal as a second element of said envelope over said sub-compact to form a compact which includes a sealed envelope of titanium based metal plasma deposited about said sub-compact, and consolidating the compact so formed at high pressure and high temperature to a relatively high density structure by direct application of fluid pressure to said envelope.
Claim 3
Dependent Claim
14 words
The process of claim 1 in which the sub-compact is a titanium base metal.
Claim 4
Dependent Claim
13 words
The process of claim I in which the metal is titanium 6Al-4V alloy.
Claim 5
Dependent Claim
13 words
The process of claim 1 in which the metal is titanium 6Al-2Sn-4Zr-2Mo alloy.
Claim 6
Dependent Claim
11 words
The process of claim 1 in which the metal is Ti-14Al-21Nb.
Claim 7
Independent Claim
126 words
The method of forming a relatively high density structure including an enclosed envelope of low pressure plasma deposited titanium base metal which comprises providing as a first element of said envelope a non-porous substrate surface onto which a plasma spray deposit can be made, superposing on said non-porous substrate a sub-compact to be consolidated to high density, low pressure RF plasma spray depositing a low porosity outer layer of metal as a second element of said envelope over said sub-compact to enclose said sub-compact in a envelope formed of said non-porous surface and said low porosity outer layer, and consolidating the compact so formed at high pressure and high temperature to form a relatively high density structure by direct application of fluid pressure to said envelope.
Claim 8
Independent Claim
126 words
The method of forming a relatively high density structure including an enclosed envelope of low pressure plasma deposited titanium base metal which comprises providing as a first element of said envelope a non-porous substrate surface onto which a plasma spray deposit can be made, superposing on said non-porous substrate a sub-compact to be consolidated to high density, low pressure RF plasma spray depositing a low porosity outer layer of metal as a second element of said envelope over said sub-compact to enclose said sub-compact in a envelope formed of said non-porous surface and said low porosity outer layer, and consolidating the compact so formed at high pressure and high temperature to form a relatively high density structure by direct application of fluid pressure to said envelope.
Claim 9
Dependent Claim
14 words
The method of claim 6 in which the sub-compact is a titanium base metal.
Claim 10
Dependent Claim
14 words
The method of claim 6 in which the metal is a titanium 6Al-4V alloy.
Claim 11
Dependent Claim
14 words
The method of claim 6 in which the metal is a titanium 6Al-2Sn-4Zr-2Mo alloy.
Claim 12
Dependent Claim
11 words
The method of claim 6 in which the metal is Ti-14Al-21Nb.
