Abstract:
The invention relates to a method for the manufacture of coatings having a low coefficient of friction on articles such as mechanical components and tools, with a layer sequence of carbon and a carbide of at least one element in the form of a metal and/or silicon and/or boron being deposited on the article by means of a PVD process. Articles which have such a layer sequence are also claimed. The coating has a low coefficient of friction, is wear-resistant and has a relatively high hardness and also relatively high elasticity.
Abstract:
A laminate structure includes an antiferromagnetic layer, a pinned magnetic layer, and a seed layer contacting the antiferromagnetic layer on a side opposite to pinned magnetic layer. The seed layer is constituted mainly by face-centered cubic crystals with (111) planes preferentially oriented. The seed layer is preferably non-magnetic. Layers including the antiferromagnetic layer, a free magnetic layer, and layers therebetween, have (111) planes preferentially oriented.

Abstract:
The invention relates to a method of applying a coating by physical vapour deposition onto an article of organic material, in particular of non- conductive organic material such as plastic and/or epoxy material, especially ABS (Acrylonitrile-Butadiene-Styrene Copolymers) and polymers with high temperature resistance, or onto an article of another composition coated with such organic material, wherein a Cr layer is deposited on the article prior to deposition of said coating to form a diffusion barrier for water coming from said article, said Cr layer itself being deposited by a physical vapour deposition process comprising at least the following steps: a) depositing a first layer of Cr on said article in a physical vapour deposition apparatus using an arc evaporator or cathode sputtering source, or in a combined arc evaporator and cathode sputtering apparatus, using zero bias, and b) subsequently applying a negative bias voltage to said article having said first layer of Cr and depositing a further layer of Cr on said first layer using Cr ions in the same physical vapour deposition apparatus.
Abstract:
A fuel cell separator which has a metal substrate and offers a high corrosion resistance and conductivity is provided. The separator has a metal layer on the surface of the substrate made of stainless steel, and a conductive layer on top of the metal layer. The conductive layer is made up of conductive particles which are fusion-bonded to each other and exhibit excellent conductivity. The separator also has a highly corrosion-resisting oxide layer which covers exposed parts of the metal layer, the parts where the metal layer is not covered with the conductive particles. This enables the fuel cell separator to assume high conductivity at an interface between the metal layer and the conductive particles, and high corrosion resistance at the exposed parts of the surface of the metal layer.

Abstract:
A pinning layer structure is provided for a spin valve sensor of a read head which has a reactively deposited nickel oxide first film which underlies a reactively sputter deposited second film of iron oxide (Fe2O3) or (Fe3O4). In the preferred embodiment the pinning layer is composed of cobalt (Co) or cobalt iron (CoFe) which is exchange coupled to the iron oxide (Fe2O3) or (Fe3O4) second film of the pinning layer. This structure results in an improved magnetoresistive coefficient (dr/R) which is substantially maintained after annealing so that the magnetic head has good thermal stability when subjected to high temperatures in the presence of a field that is antiparallel to the pinned orientation of the magnetic moment of the pinned layer.
