Oxidation of Al-Containing Austenitic Stainless Steels as Related to the Formation of Strong Glass-Ceramic to Metal Seals
Autor: R.T. Cassidy, J. C. Birkbeck, A. R. Burke, W.E. Moddeman, W. C. Bowling
Publikováno v: A Collection of Papers Presented at the 13th Annual Conference on Composites and Advanced Ceramic Materials: Ceramic Engineering and Science Proceedings
In glass-ceramic to metal seals used in pyrotechnic actuators and ignitors, Ni-based alloys and Al-containing austenitic stainless steels are used. Metal attack by the glass is severe if Ni based alloys are used, less so for the Al-containing alloys.

Sealing of Al-Containing Stainless Steel to Lithia-Alumina-Silica Glass-Ceramic
Autor: W.E. Moddeman, R.T. Cassidy
Publikováno v: A Collection of Papers Presented at the 13th Annual Conference on Composites and Advanced Ceramic Materials, Part 2 of 2: Ceramic Engineering and Science Proceedings, Volume 10, Issue 9/10
Recent work carried out on a new glass-ceramic/alloy material set for the application of pyrotechnic components is discussed. A newly developed family of austenitic stainless steels has been hermetically sealed to a widely used lithia-alumina-silica

AES and XPS of silicon nitride films of varying refractive indices
Autor: J.R. Hoenigman, W.E. Moddeman, T. N. Wittberg, M. R. Gulett, C. R. Cothern
Publikováno v: Journal of Vacuum Science and Technology. 15:348-352
AES and XPS measurements of silicon nitride films with refractive indices ranging from 1.93 to 2.08 have been made. The films studied were grown on silicon (100) substrates by CVD using varying mixtures of silane and ammonia. Earlier AES studies of s

Surface reactions of lithium with the environment
Autor: T.N. Wittberg, W.E. Moddeman, M.H. Froning, D.J. David
Publikováno v: Applications of Surface Science. 7:185-195
AES measurements have been made on clean lithium surfaces after in situ exposure to O 2 , CO 2 and N 2 . The data shows the reactions with the lithium surface occur much more rapidly for O 2 and CO 2 than for N 2 . The data on the CO 2 reaction indic
