AEROSPACE ELECTRICAL DIVISION, ALKALI METAL RESISTANT WIRE
Abstract
The program is directed toward the development of an insulated electrical conductor resistant to saturated potassium (850 C) and mercury (538 C) vapors. Some forty-seven exposure tests were initiated during the period and the test results indicated high purity alumina, magnesia, boron nitride, aluminum nitride and beryllia as well as Oxalloy 28, a stainless steel clad copper core conductor, were resistant to both environments. The fusion coating technique is the only coating process by which coated wire samples for metal vapor corrosion testing have been produced to date. In the initial screening tests, one potting compound, containing zirconia and alumina, was promising enough to merit further testing. Initial test results from trials to densify porous coatings by mass transport of material were very promising.
