Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
74 words
A method for improving the adhesion of nickel-chromium alloy films to polymeric materials wherein said alloy contains from about 65 to about 80 percent by weight of nickel, from about 10 to about 30 percent by weight of chromium and from 0 to about 10 percent by weight of iron which comprises sputtering a first thin layer of copper onto said polymeric material and sputtering a layer of said alloy onto said copper layer.
Claim 2
Independent Claim
74 words
A method for improving the adhesion of nickel-chromium alloy films to polymeric materials wherein said alloy contains from about 65 to about 80 percent by weight of nickel, from about 10 to about 30 percent by weight of chromium and from 0 to about 10 percent by weight of iron which comprises sputtering a first thin layer of copper onto said polymeric material and sputtering a layer of said alloy onto said copper layer.
Claim 3
Dependent Claim
32 words
A method according to claim 1 wherein a layer of about 25 to about 50 angstroms thick of copper is deposited as a film between a polymeric substrate and said nickel-chromium alloy.
Claim 4
Dependent Claim
18 words
A method according to claim 2 wherein said alloy film is from about 200 to 400 angstroms thick.
Claim 5
Dependent Claim
63 words
A method according to claim 1 wherein a layer of copper about 25 to about 50 angstroms thick is deposited on said polymeric material, said nickel-chromium alloy is deposited as a layer from about 200 to about 400 angstroms thick on said copper layer and a third layer about 25 to about 50 angstroms thick of copper is deposited over said alloy film.
Claim 6
Dependent Claim
16 words
A method according to claim 4 wherein a polymeric coating is disposed over said third layer.
Claim 7
Dependent Claim
16 words
A method according to claim 1 wherein a polymeric coating is disposed over said alloy film.
Claim 8
Independent Claim
69 words
A method for improving the adhesion of nickel-chromium alloy films to polymeric materials wherein said alloy contains from about 65 to about 80 percent by weight of nickel, from about 10 to about 30 percent by weight of chromium and from 0 to about 10 percent by weight of iron which comprises cosputtering said alloy with about 10 to about 15 atomic percent of copper onto said polymeric material.
Claim 9
Independent Claim
69 words
A method for improving the adhesion of nickel-chromium alloy films to polymeric materials wherein said alloy contains from about 65 to about 80 percent by weight of nickel, from about 10 to about 30 percent by weight of chromium and from 0 to about 10 percent by weight of iron which comprises cosputtering said alloy with about 10 to about 15 atomic percent of copper onto said polymeric material.
Claim 10
Dependent Claim
16 words
A method according to claim 7 wherein a polymeric coating is disposed over said alloy film.
