Abstract
Abstract A process for electroplating nickel on titanium which comprises connecting the titanium as the cathode in an acid solution to form a layer of titanium hydride on the titanium and thereafter immersing the hydrided titanium in a nickel plating solution and cathodically plating nickel thereover.

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.
