Method for treating titanium to electroplating
View Patent ↗A container method for pre-treating the inside surface of a titanium container before electroplating a metal conductive such as silver to increase adhesion for use in a lightweight alkaline battery comprising the step of applying an alkaline solution of peroxide to the surface.
1. An alkaline battery comprising:
a case comprising a titanium container the inside surface being pre-coated with a peroxide-treated layer and a silver layer,
said case enclosing:
an alkaline electrolyte;
an anode;
a cathode; and
separators to separate the anode and cathode.
2. An alkaline battery, according to claim 1 in which the inside pre-coated titanium surface;
is formed by applying an aqueous alkaline solution of a peroxide to said surface; and
reacting the titanium surface with the solution to form a rough, gray coating which will adhere strongly to said silver layer without separating from said titanium surface.
3. An alkaline battery according to claim 1 further comprising:
a silver strike layer between the treated titanium surface and the silver layer.
