Abstract:

One approach to minimizing toxic wastes is to eliminate the use of cyanide plating baths. Non-cyanide zinc plating baths have been successfully developed and have found widespread use. An investigation was conducted in an attempt to accomplish similar results with cadmium plating baths. The focus of this study was on additives to a near neutral cadmium bath, free of complexing agents. A Hull cell was used to enable visualization of deposits over a broad range of cathode current densities. Experimental design Taguchi Method was used to optimize bath parameters and constituent concentrations. Bath have been developed which indicate promise for producing dense deposits with good covering power, and relatively low tendency for hydrogen embrittlement.
