Abstract:

The program encompassed the determination of process parameters for the manufacture of continuous-length fluoridized wire production runs of up to 25 feet for several wire substrates and exploration of the variables associated with the preparation of fluoride dielectric wire coatings. Nickel chrome alloy substrates in an 8020 proportion were found to produce the best coatings, having resistance greater than 100 megohms across the coating, toughness, abrasion resistance, and the ability to withstand repeated flexure. The properties of this nickel-chrome combination were superior to those of either one of its constituent elements. Unfortunately, the coatings produced during this abbreviated program were microscopically reticulated and, therefore, permeable to the salt bath solution used for the severe high-pot tests. As a result, conduction occurred at low voltage levels. Modified author abstract
