Abstract: The Current Flow Diverter (CFD) is a promising concept for the 2nd Generation (2G) of Superconducting wires that has proven to increase the wire’s robustness against the inevitable hot-spot regime. However, since 2014 there has been a struggle in finding a practical manufacturing method for the CFD that is compatible with the coating steps of reel-to-reel systems used by companies worldwide. Using chemical solution deposition (CSD) and chemical vapor deposition (CVD) methods, four materials, i.e epoxy, graphite, yttria and silver sulfide, led to four different manufacturing routes that helped identify the main practical constrains of the CFD fabrication and, for the first time, two viable CFD fabrication routes were found with yttria nanolayers and silver sulfidation reactions.
