Abstract:
A magneto-optical recording element comprises(A) an optically transparent dimensionally stable substrate and(B) a thermally alterable recording layer which contains an amorphous lanthanide/transition metal alloy and, at least on the side facing away from the substrate (A), has a 0.1-20 nm thick surface zone containing one or more of the substances carbon, oxygen and nitrogen.
Abstract:
A planar, multilayered, laser-optical recording material comprises(a) a dimensionally stable, optically clear base material composed of a plastics substance and having a structured surface,(b) a superposed intermediate layer which is insoluble in organic solvents and which acts as a diffusion barrier thereagainst, and superposed thereon(c) an amorphous, thermally alterable, dye-containing recording layer producible by application from a solution and drying,wherein said intermediate layer (b)(b.sub.1) is from 5 to 95 nm thick and, based on (b), consists of(b.sub.2) from 88 to 99.5% by weight of an oxide and/or hydrated oxide of one or more of the elements of the group consisting of titanium, zirconium, hafnium, thorium, vanadium, niobium, tantalum, tungsten, aluminum, gallium, indium, silicon, germanium and tin and of(b.sub.3) from 0.5 to 12% by weight of a hydrocarbyl and(b.sub.4) is producible by dissolving one or more alkoxides of one or more of the abovementioned elements in a polar liquid medium essentially comprising a C.sub.1 -C.sub.6 -alkanol, applying this solution to the surface of base material (a) and heat-treating the moist layer obtainable in this way in the presence of water at from 50.degree. to 120.degree. C. for from 5 minutes to 2 hours.
Abstract:
Metallic implants with a coating of hydroxyl apatite are described. Hot isostatic pressing permits pore-free compaction of the hydroxyl apatite layer and results in firm bonding of the layer on the metallic core. The surface of the layer is partially dehydrated by means of ion bombardment, and a bioactive layer for osteogenesis is produced.
Abstract:
The present invention relates to films which are coated with at least two paint coats (2) (3), whereby the backing film (1) is coated with at least one radiation-hardenable paint coat (2) and at least one second paint coat (3), which can harden at least partially without radiation. The invention also relates to a method for producing said films and to their use for coating steel, aluminium and plastic substrates.

Abstract:
A carrier for abrasion-resistant catalysts having a surface coated with high-fusion oxides, nitrides and/or carbides of at least one transition metal, or boron, of aluminum and/or of silicon or of combination of these compounds. The coating is carried out using physical vapor deposition techniques, such as evaporating coating ion plating or cathode sputtering. The layer thus produced consists of individual structures, such as stems and/or columns having different elevations which together produce a porous layer serving as an intermediate layer for the subsequent deposition of the catalytic material.
