The invention concerns a sliding body for sliding systems in which sliding surfaces of sliding and counter components form a gap in which there is a fluid, whereby the sliding body (1) at least in the area of sliding surfaces (10) is comprised of several stacked thin form elements stamped out of foils or cards, which are solidly bonded together on the contact faces. The invention also concerns a process for the production of the sliding body, whereby foils are produced from ceramic slips, in which various hollow chambers and/or recesses are stamped or impressed, a laminating agent is applied to the foils or cards, the foils or cards are stacked into a sliding body packet and the layers of the stack are laminated together, the organic components are partially baked off, after which a post-treatment of the sliding body takes place, then the remainder of the organic components are removed, and then the laminated sliding body is sintered between 1200.degree. and 2200.degree. C., after which an optional post-treatment takes place. The novel sliding body is used especially for production of hydrodynamic enhancement shapes in the sliding surface. |

A firmly adherent film 16 of bondable metal, such as silver, is applied to the surface 10 of glass or other substrate by decomposing a layer 14 of a solution of a thermally decomposable metallo-organic deposition (MOD) compound such as silver neodecanoate in xylene. The MOD compound thermally decomposes into metal and gaseous by-products. Sealing is accomplished by depositing a layer 18 of bonding metal, such as solder or a brazing alloy, on the metal film and then forming an assembly with another high melting point metal surface 20 such as a layer of Kovar. When the assembly is heated above the temperature of the solder, the solder flows, wets the adjacent surfaces and forms a hermetic seal between the metal film 14 and metal surface 20 when the assembly cools. |

A composite wafer bonded to a carbide substrate is formed by preparing a dispersion of super-hard crystals and carbon black in a temporary binder such as paraffin, by preparing a base mixture of carbon fiber, carbon black and filler in the temporary binder, and by preparing an additional mixture of cobalt and carbon black in the temporary binder. The dispersion, base mixture and additional mixture are compacted to form an intermediate composite, the additional mixture forming a layer on one surface of the base mixture. The intermediate composite is heated to allow for the removal of the temporary binder and the infiltration of liquefied silicon into the composite which is then reaction sintered to form the composite wafer. |

A ferrite-to-metal bond suitable for the environment of a high-power microwave circulator is disclosed. The bonding surface of a gyromagnetic ferrite or garnet button is metallized by a sputtering process that deposits successive layers of nichrome, copper and gold thereon. During the sputtering process, a flexible stainless steel band surrounds the button to prevent sputtered material from being deposited on other than the bonding surface of the button. The metallized bonding surface is then soldered to a metal wall of the circulator. The bond so formed is capable of withstanding a peak power level in the circulator of 2.0 megawatts and an average power level of 3.5 kilowatts under standing-wave conditions. |

A turbine blade with a ceramic thermal barrier coating system has a substrate designed as a blade platform and as a blade airfoil. On the substrate is a first ceramic layer as a thermal barrier coating, which protects the substrate in the exposed high temperature region and there is locally an increase of the thermal barrier coating for locally reinforcing the thermal barrier. The increase includes a material that is different from the material of the first ceramic layer. The local reinforcement is arranged over the first ceramic layer, without the first ceramic layer having a reduced layer thickness. The local reinforcement is provided at most on 30% of the area of the blade airfoil and is arranged close to a platform extending over the entire pressure side in the direction of flow and with an extent thereto in the radial direction of the blade airfoil is at most 30%. |
