  • Patent number: 8947826
    Abstract: A durable wear-resistant coating consists of an atomically mixed layer on the surface of the head or media which is developed by bombardment of the surface with energetic C ions with optimized parameters. This mixed layer is covered with a hard DLC overcoat. This mixed interlayer is able to strongly bond the overcoat to the head or media substrate and improve the tribological properties of the overcoat. In this method a very thin layer of a carbide former material can be used as an interlayer before bombarding the surface with C ions which provides a composite interlayer containing C and species from interlayer and substrate. This composite interlayer bonds the DLC overact to the ceramic substrate of the head or the metallic substrate of the media. This interlayer by itself is protective enough to protect the head media of the hard drives against wear and corrosion.

    Abstract: A process for forming a coating on a surface of a substrate, so that heating of the coating material is selective and sufficient to cause at least partial melting of the coating material and permit bonding to the substrate without excessively heating the substrate so as not to significantly degrade its properties. The process generally entails forming a brazing paste containing powder particles dispersed in a binder. The particles are formed of a composition that is susceptible to microwave radiation. The brazing paste is then applied to the surface of the substrate and subjected to microwave radiation so that the particles couple with the microwave radiation and are sufficiently heated to burn off the binder and then at least partially melt to form an at least partially molten layer on the substrate. The microwave radiation is then interrupted to allow the at least partially molten layer to cool, solidify, and form the coating.

  • Patent number: 8524051
    Abstract: A coated article is provided that may be heat treated in certain example embodiments. A graded layer (e.g., contact layer or other suitable layer) is formed by initially sputter-depositing a layer, and thereafter ion beam treating the sputter-deposited layer with at least reactive gas ions in order to form a graded layer. In certain example embodiments, the result is a coated article that has improved visible transmission and/or durability, without sacrificing optional heat treatability.

  • Publication number: 20130177713
    Abstract: A method is provided for forming a coating layer on a surface, wherein the coating composition includes at least two reactive components. At least one of the components is encapsulated in a plurality of microspheres, which are then mixed with the second component in a single chamber of a container. The mixture is sprayed from the chamber through a single spray nozzle onto the surface. Then, the microspheres degrade to release the first component and allow the first and second components to react with one another, thereby forming the coating layer on the surface.

  • Patent number: 8470095
    Abstract: A process for surface preparation of a substrate (2), which comprises introducing or running a substrate (2) into a reaction chamber (6, 106). A dielectric barrier (14, 114) is placed between electrodes (1, 10, 110). A high-frequency electrical voltage is generated, to generate filamentary plasma (12, 112). Molecules (8, 108) are introduced into the reaction chamber (6, 106). Upon contact with the plasma, they generate active species typical of reacting with the surface of the substrate. An adjustable inductor (L) placed in parallel with the inductor of the installation is employed to reduce the phase shift between the voltage and the current generated and to increase the time during which the current flows in the plasma (12, 112).

  • Patent number: 8394197
    Abstract: Enhanced corrosion resistance is achieved in a coating by using a germanium-containing precursor and hollow cathode techniques to form a first layer directly on the surface of a workpiece, prior to forming an outer layer, such as a layer of diamond-like carbon (DLC). The use of a germanium or germanium-carbide precursor reduces film stress and enables an increase in the thickness of the subsequently formed DLC. Germanium incorporation also reduces the porosity of the layer. In one embodiment, a cap layer containing germanium is added after the DLC in order to further reduce the susceptibility of the coating to chemical penetration from the top.
