This project addresses the induced codeposition of molybdenum and tungsten alloys with nickel and iron with a focus on developing a toolbox of plating conditions to deposit different combinations of Ni, Fe, Mo and W. The experimental approach will utilize electrodes with a controlled hydrodynamic environment, since it has been noted by the project director that the reduction mechanism can involve a coupled kinetic-mass transport behavior. The project was initiated in January 2013 and as of April 15, 2013, we have started three different sub-projects, in parallel, utilizing a Hull cell, a rotating Hull cell and a rotating cylinder electrode.
