ABSTRACT:
A method to produce an electrode by coating at least a portion of a valve metal substrate sequentially with first and second liquid solutions containing different proportions of dissolved ruthenium and valve metal values; the second solution having a greater valve metal to ruthenium weight ratio than the first solution. At least a portion of the substrate is contacted with a first liquid solution containing ruthenium and the valve metal in amounts of from about 1 to about 50 milligrams per milliliter of the solution. The weight ratio of the valve metal to ruthenium in the first solution is from about 1:4 to about 2:1. The so-contacted surface is heated to oxidize the deposited ruthenium and valve metal values. Thereafter at least the oxidized surface is contacted with a second solution containing dissolved valve metal and ruthenium values in a weight ratio of from about 20:1 to about 2:1 and heated to oxidize the deposited metal values.
