irnsrgn Posted June 27, 2008 Share Posted June 27, 2008 Joe, I am wondering if the solution to your sign problem is sandwiching a buffer material between the Al and Fe so that the expansion and contraction does not affect the bonding material. ie, a thin strip of silicone, weather stripping, etc. Quote Link to comment Share on other sites More sharing options...
clang Posted July 20, 2008 Share Posted July 20, 2008 There are a couple of multistep methods Firegirl, but they are a nuisance. I read a 1930s method than ran to 13 layers and another , later one that ran 7 layers. There is, or was, an AC aluminum-bronze rod that will deposit on freshly scraped aluminum and an AC phos-bronze rod that will lay down on that ,as well as steel. A little tricky but possible...pf Quote Link to comment Share on other sites More sharing options...
chiso Posted July 20, 2008 Share Posted July 20, 2008 That is what it is called. The Australian navy mine sweepers??? Used to have there ships made with steel hulls and an aluminium deck to keep the weight down. But in an explosion they found that the deck pealed away from the hull. Would cost a fortune to do.
