Abstract:

Particle bombardment chemistry and thermal chemistry are compared. Particle bombardment techniques for crystal growth welding and bonding are discussed. The nine different sputter arrangements used in this study for producing ion bombardment bonded coatings are described. All of them use high frequency energy for plasma generation and most of them utilize magnetic plasma confinement. Combinations of the following insulating materials and metals have been particle bombardment bonded, vacuum brazed or pressure sealed and tested for tensile strength. Insulating Materials Al2 O3 Al 995, CE 988, WESGO, Lucalox, G.E BeO Thermalox Brush-Beryllia Si O2 Quartz, Vicor Glass 1723 Corning Pyroceram Corning and also Ferrites. Primary Metals Zr, Ti, V, Nb, Ta, Mo, W, Al and Alloys Molybden-Tungsten 50, Stainless Steel 304, Nichrome 18 and 35 Cr. and Kanthal. Secondary Metals Cu, Ag, and Au. Tensile Strength Results are tabulated for all tests.
