摘要:
Die Erfindung betrifft eine Vorrichtung (1) zur Herstellung eines mit zumindest einer Korrosionsschutzschicht (K) beschichteten magnesiumhaltigen Substrats (S). Erfindungsgemäß ist ein Umformwerkzeug (2) zur Umformung des Substrats (S) vorgesehen und in das Umformwerkzeug (2) sind bzw. ist eine Flammenbeschichtungseinheit (3) und/oder eine Plasmabeschichtungseinheit (5) zum Auf- und/oder Einbringen der zumindest einen Korrosionsschutzschicht (K) unmittelbar nach einem Umformprozess, zwischen mehreren Umformprozessen und/oder vor einem Umformprozess integriert. Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung eines mit zumindest einer Korrosionsschutzschicht (K) beschichteten magnesiumhaltigen Substrats (S). Erfindungsgemäß wird das Substrat (S) mittels eines Umformwerkzeugs (2) umgeformt und auf und/oder in das Substrat (S) wird innerhalb des Umformwerkzeugs (2) unmittelbar nach einem Umformprozess, zwischen mehreren Umformprozessen und/oder vor einem Umformprozess mittels einer in das Umformwerkzeug (2) integrierten Flammenbeschichtungseinheit (3) und/oder Plasmabeschichtungseinheit (5) die zumindest eine Korrosionsschutzschicht (K) auf-und/oder eingebracht.
摘要:
An apparatus and method for forming a thin film on a substrate by RPCVD which provides for very low levels of carbon and oxygen impurities and includes the steps of introducing a Group VA plasma into a first deposition zone of a growth chamber, introducing a Group IIIA reagent into a second deposition zone of the growth chamber which is separate from the first deposition zone and introducing an amount of an additional reagent selected from the group consisting of ammonia, hydrazine, di-methyl hydrazine and a hydrogen plasma through an additional reagent inlet into the second deposition zone such that the additional reagent and the Group IIIA reagent mix prior to deposition.

A method for thermochemically treating a part while masking a portion and corresponding mask are provided. The method includes the steps of providing a mask comprising a body with a seat, at least a deformable sealing washer located in the seat, and a tightening bushing, the body having a cavity, placing a first portion of the part in the cavity, a second portion of the part being located in a passage in the sealing washer, and a third portion of the part being located outside the mask, moving the tightening bushing to its tightened position so that the sealing washer is deformed and applied against the second portion of the part, and applying a thermochemical treatment to the third portion of the part.

摘要:
The present invention provides an advantageous method for producing a coating which increases the friction coefficient (3) on a surface (5) of a component (6), wherein the method comprises the following steps: a) activating hard particles (1) that are coated in part or entirely by an adhesive (2) in a non-thermal plasma (low-temperature plasma) under atmospheric pressure; and b) producing the layer (3) which increases the friction coefficient on the surface (5) of the component (6) by depositing the hard particles (1) activated by the non-thermal atmospheric pressure plasma and coated with the adhesive (2) on the surface (5) of the component (6). Said method is particularly more economic for components with complex forms or large dimensions than known methods. No matrix or intermediary layers are required for anchoring the hard particles. The hard particles engage directly in the contact surfaces.
