<p>Encapsulated ferrite magnetic memory cores are disclosed which have a very thin coating of polymerized gamma-aminopropyltriethoxysilane, whereby the cores are organophilic for adhesion to an uncured silicone rubber-coated substrate, are lubricated to minimize friction with wires passed through the holes in the cores, and are hydrophobic to provide moisture-repellence of the cores in use in a memory. The cores are encapsulated by shaking a substantial bulk quantity of sintered ferrite memory cores in silane vapor at a temperature of about 220 DEG C. in an inert gaseous environment having a known moisture content.</p> |
