Current Topic:
Stainless Steel reaction to Aluminum in Salt Water

Steve, an anodized layer will certainly help, although you want to make certain that your anodized layer is sealed.  By making the aluminum non-conductive, you eliminate the battery that forms between the 6061 and the 316, greatly reducing the corrosion on the 6061 piece.  Yet anodizing isn't the final answer, as anodizing and painting is better, and if you can further isolate the joint, with say some kind of potting compound, you'll be even better off.

 

Good luck!
