Procedure
After the roughened titanium substrate surface was heat treated, it was painted with a n-butanol solution containing salts of iridium and tantalum. The ratio of iridium to tantalum in the solution was about 65% to 35% by weight. The solution was allowed to dry at ambient temperature for approximately 20 minutes. The painted titanium substrate was subsequently heat treated in a furnace having an oxygen containing atmosphere at approximately 500° C. for approximately 20-30 minutes to form an iridium oxide/tantalum oxide composite coating. The process of painting and heat treating the titanium substrate was repeated to obtain a first layer having a total loading of 2.0 g/m2. After the desired loading was achieved, the anode was heat treated for approximately one hour at approximately 500° C.
