Procedimiento

After the titanium substrate surface was roughened, it was painted with a n-butanol solution containing salts of iridium and tantalum in a ratio of iridium to tantalum of approximately 65% to 35% by weight. The applied 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 in order to obtain a total loading of about 2.0 g/m2. After this loading was achieved, the painted substrate was heat treated for approximately one hour at approximately 500° C.
