The Electrodeposition of Platinum and Platinum Alloys

Work on the electrolytic deposition of platinum and some platinum alloys is reviewed, and the results of our recent work OR the deposition and the proper-ties of the layers produced from some promising electrolytes are briefly dis-cussed. In general, studies of plating solutions are restricted by the economic availability of the relevant platinum salts. On the other hand the hydrolysis of the platinum salts in solution, and the incorporation of decomposition pro-ducts are also critical factors, especial-ly for their influence on internal stress. Recent work has shown that i t is possi
