Platinum black electroplating [Alabama] 

+++++

I am trying to do platinum black electroplating using ysi 3140 platinizing solution. But I get either clustered or non uniform platinum black coating. Can anybody suggest, how to do a uniform platinum black coating.

There is a procedure for coating conductivity electrodes with platinum black in the "Conductivity" chapter of "Standard Methods for the Examination of Water and Wastewater" that might be of help to you.
