Patent DE-4237980-A1 (DE)
Title: Prodn. of multilayered nitrated or nitride coating by reactive plasma spraying - in which successive layers are sprayed onto base layer with step increases of partial pressure of nitrogen in the plasma jet
Inventor: JAEGER DORIS DR ING
IPC: C23C4/10
Filed: 1992-11-11
Abstract: A multilayered nitrated or nitride coating is produced by reactive plasma spraying, with supply of a reactive metal powder. It includes the following process steps: (a) a reactive metal base layer at least 30 micron thick is first applied to a preheated substrate with the use of a plasma gas free from reactive gases in an inert gas atmosphere in the spraying chamber, at a pressure of at least 30 mbar; and (b) several individual layers, each at least 30 micron thick, are then successively sprayed onto the base layer, with the partial pressure of nitrogen in the plasma jet (and thus in the vicinity of spray particles) increased stepwise from layer to layer. The partial pressure of nitrogen in the plasma jet is stepwise increased in such a way that the last layer consists of pure reactive metal nitride. The pressure in the spraying chamber is increased stepwise by appropriate increases in the nitrogen supply. Liquid nitrogen is used to cool at least temporarily the coatings produced. USE/ADVANTAGE - For production of multilayered coatings for various purposes (e.g. for sliding bearings).

Title: Rotor-type nozzle for a high-pressure cleaning unit
Inventor: JAEGER ANTON
IPC: B05B1/16
Filed: 1993-06-15
Abstract: In order, in the case of a rotor-type nozzle which is provided, in particular, for a high-pressure cleaning unit, to bring about a change in the spraying angle and, at the same time, to permit a self-regulating restriction of rotational speed, it is proposed to provide a longitudinal groove (22) on that side of the nozzle rotor (4) remote from the nozzle bearing (6), a central bearing pin (21) opening into said longitudinal groove. By virtue of corresponding flow taking place against the nozzle rotor (4), the latter is then pressed towards the inner wall of the swirl-chamber pressure housing (1), this resulting in a self-regulating braking action.

The magnet system is arranged in a guide ring which surrounds the enamelled guide pipe and is fastened to the float. The float is of spherical design and from the upper end of the float there project two pipe attachments which are enamelled on the outside and to which the guide ring is fastened. Furthermore, a method for producing and enamelling a float of this type is described, the surface of the float, which is produced from steel sheet, and the pipe attachments being coated with enamel frit before each firing and the pipe attachements being used for setting up or suspending the hollow body during each firing. After the enamelling of the hollow body, the open ends of the pipe attachments are welded closed and ground. After this, the closed ends of the pipe attachments are locally enamelled over.

Title: Process for wave soldering using lead-free solders
Inventor: WANDKE ERNST DIPL ING DR ING
IPC: H05K3/34
Filed: 1993-11-09
Abstract: The invention relates to a process for wave soldering subassemblies, in particular printed-board assemblies, with shielding of the surroundings, in which lead-free or at least low-lead solders, in particular tin solders, having a melting point of more than 210 DEG C are used. Since in wave soldering, the solder bath temperature usually has to be set significantly higher than the melting point of the respective solder, overheating problems in the components to be soldered occur with the relatively high-melting, lead-free or low-lead solders. As a solution to this problem, it is proposed according to the invention that a solder bath temperature of only a few degrees Celsius above the melting point of the respective solder be set and that the wave soldering process be carried out under the plasma action of a process gas atmosphere under low pressure.
