Abstract: A process for applying a metal layer to surfaces of light metals is proposed, in which iron is electrolytically deposited on the surfaces from a deposition bath containing Fe(II) compounds using dimensionally stable anodes insoluble in the deposition bath. The process is especially suitable for coating cylinder faces of internal combustion engines and of rotationally symmetrical parts with layers having very high wear resistance, especially of valves, nozzles and other parts of high-pressure injection systems for motor vehicle engines. In addition, the present invention pertains to nanocrystalline iron-phosphorus layers, which can be formed preferably by depositing iron in the presence of compounds containing orthophosphite and/or hypophosphite. These layers also have good corrosion resistance besides the good wear resistance.

Particularly, an improved method of producing such sheeting and bonding it to a backing layer for use as various types of wound dressings and scar management products. The new process represents several improvements over previous techniques as follows: a) single-pass process, b) no second coating of liquid polymer required to act as glue, c) no solvents or other processing aids required, d) no additional oven length needed to effect the required dwell time, e) increased line speed relative to prior techniques, and g) the carrier substrate 20 need only be coated with a release surface on one side.

Abstract: In the production of printed circuit boards it is required that organic protective coatings adhere tightly on the copper surfaces. Accordingly, matt layers of copper are to be preferred over lustrous coatings. The bath in accordance with the invention serves to deposit matt layers of copper and has the additional advantageous property that the layers may also be deposited with sufficient coating thickness in very narrow bore holes at average cathode current density. For this purpose the bath contains at least one polyglycerin compound selected from the group comprising poly(1,2,3-propantriol), poly(2,3-epoxy-1-propanol) and derivatives thereof.

Abstract: A method of passivating the surface of a substrate to protect the surface against corrosion, the surface effects on a vacuum environment, or both. The substrate surface is placed in a treatment environment and is first dehydrated and then the environment is evacuated. A silicon hydride gas is introduced into the treatment environment, which may be heated prior to the introduction of the gas. The substrate and silicon hydride gas contained therein are heated, if the treatment environment was not already heated prior to the introduction of the gas and pressurized to decompose the gas. A layer of silicon is deposited on the substrate surface. The duration of the silicon depositing step is controlled to prevent the formation of silicon dust in the treatment environment. The substrate is then cooled and held at a cooled temperature to optimize surface conditions for subsequent depositions, and the treatment environment is purged with an inert gas to remove the silicon hydride gas.

Abstract: A thrust bearing 11 for use with a shaft 13 having a collar 15 mounted the shaft 13 and rotatable therewith has a base ring 17, a series of shoes 19 positioned on the base ring 17, and a compressible resilient spacing member 29 positioned between the base ring 17 and a housing 31 for the thrust bearing 11. The spacing member 29 supports the thrust bearing 11 when the shaft 13 is rotating during no-load operating conditions, as well as dampens the forces placed on the thrust bearing 11 by the shaft 13 when the shaft 13 is rotating during no-load conditions. The spacing member 29 is sufficiently stiff that it supports the thrust bearing 11 when the shaft 13 is rotating under no-load conditions, but is sufficiently compressible to be compressed to the extent that the gap 33 between the base ring 17 and the housing 31 is eliminated due to the forces placed on the thrust bearing 11 by the shaft 13 bringing the base ring 17 into contact with the housing 31 during normal load operating conditions.
