Abstract:

The report documents the complete test program conducted to establish a seat and poppet materials for use in chlorine pentafluoride ClF5 attitude control system ACS valves. Test results of iron, nickel, tungsten, boron and zirconium based materials in the flat-on-flat sealing concept are discussed. Additionally, a sapphirecopper lip-seal concept and thin coatings of aluminum, tungsten and chromium on substrates, previously proved to be incompatible, were evaluated. In the tests conducted under this program, two carbides of tungsten and one of boron have successfully met the helium leakage requirement after 100, 000 actuations in the ClF5 environment.
