Abstract : In addition to copper, the metals silver, aluminum and titanium were sputtered in their own vapors by their own ions and this process was used for metalizing ceramics and ferrites. Attention was given to metals with strong adherent protective oxide coatings as base metals for particle bombardment metalizing of ferrites and ceramics. The metals studied are chromium, aluminum and some of their alloys, such as stainless steel 304, nichrome with 18% and 35% chromium, and kanthal. Tensile test results of these metals and of titanium on alumina 995 are given. On ferrites in addition to these metals, nickel, iron and cobalt were used as base metals. Bonding to the ferrites was checked only qualitatively by peeling tests. Best results are obtained with nichrome and chromium as base metals. The alumino-silicate glass, Corning 1723 was successfully metalized and brazed with silver-copper eutectic. Pictures of cone growth on copper, gold, tantalum and tungsten are shown. (Author)
