New Materials: Modumetal's Nanolaminate Alloys, Grown in a Tank, Outperform Steel
Sounds like a very interesting prospect. I would be interested to see how it performs with classical fabrication techniques. I would be interested in performance of weldability, bending, cutting, grinding.
This sounds like really, really thick electroplating. With different cathodes in the solution, they might even be able to layer different materials without even transferring it to a different container. For their corrosion resistance, are they electroplating on a really thick layer of zinc instead of dipping it in molten fluid.
Most likely just electroplating. There have been limits to which metals can be combined and plated together, mostly do due the salt water electrolyte. Some metals require high currents and voltages in order to be plated and the water in the electrolyte starts to boil from the temperature and splits into hydrogen and oxygen from the current.
