          Appeal No. 1997-2097                                                        
          Application No. 08/191,137                                                  


               Loch (column 5, lines 4-64) discloses the plating of                   
          aluminum substrates using a zincate protective coating                      
          followed by an electroless nickel coating (strike) and then an              
          outer conductive metal plating, with tin being the only                     
          exemplified metal for that outer coating.  Loch (column 7,                  
          lines 28-30) discloses that an "[e]lectroless nickel plate was              
          found to be a superior barrier layer than was electrodeposited              
          copper" for the obtention of a blister free tin plating of                  
          porous aluminum castings.                                                   
               Shemenski (abstract) is directed to the formation of a                 
          ternary brass alloy coated steel wire element that may be used              
          in reinforcing rubber articles.  In making that coated steel                
          wire element, Shemenski teaches that copper, zinc and iron may              
          be deposited on the steel elements followed by heating to                   
          promote diffusion of the deposited metals to form the brass                 
          coating (column 3, line 58 through column 4, line 3).                       
          Shemenski discloses that the iron layer used in making the                  
          brass coated steel element may be deposited using                           
          electroplating solutions selected from "iron chloride                       
          solutions, iron sulfate solutions, iron fluoroborate                        
          solutions, and ferrous ammonium sulfate solutions" (column 4,               
                                       Page 5
