CLAIMS:
A method for producing a platinum plated titanium anode which comprises, electrode posting a coating of amorphous platinum on a titanium member and activating said platinum coating by heating at a temperature above about 600*F. In the presence of an air stream containing hydrocarbon vapors for a period of time sufficient to initiate catalytic oxidation of such vapors on the platinum surface.
DESCRIPTION:
The platinum surface is preferably deposited by an electroplating operation whereby a thin fixed coating of platinum covers the entire surface of the unit. The electrode position may be carried out, for example, by using a bath consisting of 4.5 grams of platinic chloride and 22 milliliters of 37% hydrochloric acid dissolved in 2800 milliliters of water. The temperature is maintained between F. and F. and current intensity is such that no hydrogen is evolved at the titanium panel. A graphite anode is used in the bath and the titanium panel is made cathodic. The panel is moved or agitated during the plating operation. Also, current flow is regulated to preclude hydrogen involvement at the panel cathode, while coating to approximately 1 mm. in thickness of platinum in a two minute period of time. However, it may be pointed out that minor variations may be made in effecting the deposition of the noble metal and that varying thicknesses may be obtained by suitable modifications in the time consumed in the electroplating operation. Deposition of other metals of the platinum group may be carried out in a similar manner. Also, simultaneous deposition may be made of more than one component, as, for example, by effecting a coating from a solution containing another element along with platinum, such as iridium or caesium. Such other component being added to the electroplating bath whereby a desired resulting composite is obtained in the electrode position.
