Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
89 words
Process of forming and applying a layer of a reaction product to a surface of a base, which comprises: bringing together at least two chemically different components, one of which is an electric conductor, and the other is a solid or liquid in imediate contact therewith, in immediate proximity to said base, and explosively forming a reaction product of said components by effecting a surge current discharge through said conductor, thereby generating a plasma state in which said formed reaction product is hurled against the surface of said base.
Claim 2
Dependent Claim
89 words
Process of forming and applying a layer of a reaction product to a surface of a base, which comprises: bringing together at least two chemically different components, one of which is an electric conductor, and the other is a solid or liquid in imediate contact therewith, in immediate proximity to said base, and explosively forming a reaction product of said components by effecting a surge current discharge through said conductor, thereby generating a plasma state in which said formed reaction product is hurled against the surface of said base.
Claim 3
Dependent Claim
15 words
Process according to claim 1, wherein a material component is present in the solid state.
Claim 4
Dependent Claim
15 words
Process according to claim 1, wherein a material component is present in the liquid state.
Claim 5
Dependent Claim
19 words
Process according to claim 1, wherein the electrically conducting component of the material envelops the other component or components.
Claim 6
Dependent Claim
21 words
Process according to claim 1, wherein the electrically conducting component of the material is enveloped by said other component or components.
Claim 7
Dependent Claim
14 words
Process according to claim 1, wherein the conductor proper is a chemically reactive component.
Claim 8
Dependent Claim
29 words
Process according to claim 1, wherein the reaction components are arranged in immediate proximity to the base to be coated by vapor or form the surface of this base.
Claim 9
Dependent Claim
18 words
Process according to claim 1, wherein at least one gaseous reaction component is present within one reaction area.
Claim 10
Dependent Claim
15 words
Process according to claim 4, wherein the other component consists of an explosive reaction mixture.
