Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
55 words
A process for electro-plating nickel on titanium which comprises connecting titanium as the cathode in an acid electrolyte capable of forming a layer of titanium hydride on the titanium and forming a layer of titanium hydride on said titanium; and thereafter immersing the hydrided titanium in a nickel plating solution and cathodically plating nickel thereover.
Claim 2
Dependent Claim
55 words
A process for electro-plating nickel on titanium which comprises connecting titanium as the cathode in an acid electrolyte capable of forming a layer of titanium hydride on the titanium and forming a layer of titanium hydride on said titanium; and thereafter immersing the hydrided titanium in a nickel plating solution and cathodically plating nickel thereover.
Claim 3
Dependent Claim
13 words
The process of claim 1 characterized in that the electrolyte is sulfuric acid.
Claim 4
Dependent Claim
20 words
The process of claim 1 characterized in that the nickel plating solution comprises nickel sulfate, nickel chloride and boric acid.
Claim 5
Dependent Claim
25 words
The process of claim 1 characterized in that oxide on the surface of the titanium is removed prior to formation of the titanium hydride layer.
Claim 6
Dependent Claim
46 words
A process for electroplating nickel on titanium which comprises cleaning and removing any oxide from the surface of the titanium, cathodically forming a layer of titanium hydride on the surface of the titanium in an acid capable of forming titanium hydride and cathodically plating nickel thereover.
Claim 7
Dependent Claim
46 words
A process for electroplating nickel on titanium which comprises cleaning and removing any oxide from the surface of the titanium, cathodically forming a layer of titanium hydride on the surface of the titanium in an acid capable of forming titanium hydride and cathodically plating nickel thereover.
Claim 8
Dependent Claim
19 words
The process set forth in claim 5 characterized in that a lead plating is applied over said nickel plate.
Claim 9
Dependent Claim
27 words
As an article of manufacture a grid support for a cathodic reactant for lead-sulfuric acid storage battery cells made according to the process described in claim 1.
Claim 10
Independent Claim
87 words
The method of producing a titanium base grid support for leadsulfuric acid storage batteries which comprises cleaning and removing oxide from the surface of a titanium grid, connecting the titanium as the cathode in an acid solution capable of forming titanium hydride and forming a layer of titanium hydride on the surface of the titanium, immersing the hydrided titanium in a nickel plating solution and cathodically plating nickel thereover to form an adherent bond with the titanium and thereafter cathodically plating lead on the nickel coated titanium.
Claim 11
Independent Claim
87 words
