A metal shaft is joined to a permanent magnet by a seal formed of a thin layer of a metal on the magnet which forms a bond with the magnet. A layer of a solorable metal provided on the thin layer and a layer of a low melting point solder contacting the metal shaft and layer of solderable metal.

Method of mounting permanent magnets without organic adhesives

A permanent magnet of a hard magnetic material, such as rare earth-cobalt intermetallic compounds or AlNiCo, is joined to a mounting surface by way of intermediate layers. These layers avoid heating the magnet above the maximum service temperature of the magnetic material, and thus prevent losing the magnetic properties.

Mounting hard magnetic material permanent magnets

A reliable garnet to metal hermetic seal is obtained by metallizing the garnet with successive sputtered layers of tantalum or titanium, molybdenum or tungsten and nickel, followed by soldering or brazing the metallized garnet to a metal member.

An improved hermetically sealed glass encapsulated monolithic ceramic capacitor in which a metallurgical bond between the capacitor termination and the end cap of its lead is effected by means of brazing.

Beryllium to metal seals are produced by forming on a beryllium surface by cathode sputtering a first metal layer from a group of metals including tantalum, niobium, zirconium, hafnium, titanium or vanadium, an intermediate cathode sputtered layer of a refractory metal and outer layer of a readily brazable metal and soldering the readily brazable layer to another metallic body.
