Abstract
Abstract The invention relates to a process for treating an elongated, coated substrate, whereby treatment comprises the application by cathode sputtering of a material containing at least one component and whereby the composition of this material has been chosen in accordance with the difference between the composition of the coating or the surface of the coating as measured and the desired composition of the coating or the surface of the coating.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
60 words
A process for treating an elongated substrate comprising the steps of: forming the substrate of steel; applying to the steel substrate a first coating of brass by a non-sputtering technique, wherein the first non-sputtered coating is applied with a thickness of 0.1 to 0.35 microns; applying by cathode sputtering a second coating to the substrate, the second coating being cobalt.
Claim 2
Dependent Claim
60 words
A process for treating an elongated substrate comprising the steps of: forming the substrate of steel; applying to the steel substrate a first coating of brass by a non-sputtering technique, wherein the first non-sputtered coating is applied with a thickness of 0.1 to 0.35 microns; applying by cathode sputtering a second coating to the substrate, the second coating being cobalt.
Claim 3
Dependent Claim
30 words
The process according to claim 1, comprising sputtering the second coating with one of an inert sputtering gas and a gas having an inert sputtering gas with a reactive gas.
Claim 4
Dependent Claim
18 words
The process according to claim 1, further including leading the elongated substrate longitudinally through a cathodic elongated casing.
Claim 5
Dependent Claim
17 words
The process according to claim 3, further comprising forming said elongated casing with a cylindrical inner surface.
Claim 6
Dependent Claim
15 words
The process according to claim 3, further comprising keeping said elongated substrate at ground potential.
Claim 7
Dependent Claim
21 words
The process according to claim 5, further comprising applying an alternating potential to said elongated substrate and said cathodic elongated casing.
Claim 8
Dependent Claim
23 words
The process according to claim 1, further comprising moving an inert sputtering gas and said elongated substrate in opposite directions through a cathode.
Claim 9
Dependent Claim
21 words
The process according to claim 7, further comprising replacing a portion of said inert sputtering gas by a sulphur containing gas.
Claim 10
Dependent Claim
20 words
The process according to claim 7, further comprising replacing a portion of said inert sputtering gas by a nitrogen gas.
Claim 11
Dependent Claim
15 words
The process according to claim 1, further comprising cleaning said elongated substrate by plasma cleaning.
Claim 12
Dependent Claim
15 words
The process according to claim 10, further comprising cleaning said elongated substrate by induction heating.
Claim 13
Dependent Claim
21 words
The method recited in claim 1 wherein the second sputtered coating is applied with a thickness of 20 to 500 Angstroms.
Claim 14
Dependent Claim
21 words
The method recited in claim 12 wherein the second sputtered coating is applied with a thickness between 50 and 200 Angstroms.
