A holder for holding a metal component part, which has at least one internal passage which is accessible by an opening in an external surface of the component part. The holder is equipped with a bearing element, which comprises a bearing surface, which is designed in such a way that it allows a seating of the component part on the bearing element, and in this case serves as a support for at least a part of the external surface of the component part which has the opening, and a flow passage, which leads through the bearing element, with at least one outlet opening located in the bearing surface. The outlet opening is located in the bearing surface in such a way that, with the component part seated, it lies opposite the opening of the internal passage. Furthermore, the outlet opening in shape and flow cross section is adapted to the opening of the internal passage.

The invention relates to a peening device for peening a component with a part to be peened and a part not to be peened. The peening device comprises a chamber with at least one opening located therein, wherein the opening is dimensioned in such a manner that the part not to be peened of the component can be guided there through, and a fixture for retaining the component which features a section which entirely covers the opening of the chamber when the part not to be peened is at least partially guided into said opening, and said section completely encloses the part not to be peened of the component between the adjacent region of the part to be peened of the component and the opening.

A method for coating of a component part is made available, in which an evaporating of a coating material from a material feeder at low ambient pressure is brought about. The component part which is to be coated is located sufficiently near to the material feeder in such a way that, as a result, a depositing of vaporized coating material on the surface of the component part is brought about. A rotation of the component part around a rotational axis takes place while it is located sufficiently near to the material feeder for the bringing about of the depositing of coating material. The rotational axis is pivoted from a standard position towards the material feeder before or during the coating.

摘要:
Coatings which are applied to a component have to be removed again in a complex way in certain regions, since a coating was not desired to be present in those regions. The subsequent removal of this layer adversely affects the component, for example its geometry. The method according to the invention for coating a component includes a masking which at least partially comprises a ceramic powder and can therefore easily be removed after the component has been coated.
摘要:
A method is provided for coating a component with a multilayer ceramic coating in which the individual layers of the ceramic coating are applied covering one another on the component, and in which ceramic particles are supplied to a coating burner, melted partly or completely by the coating burner, and deposited on the component. The ceramic particles have a particle size, which increases from layer to layer, and are supplied to the coating burner. Furthermore, a multilayer ceramic coating and a component which has with a multilayer ceramic coating are provided.

摘要:
Coatings that are applied to a component have to be removed again from certain areas using costly methods, because coating was not required in those areas. The subsequent removal of this layer can impair the component, for example in terms of its geometry. The inventive method for coating a component uses a mask, which consists at least partially of a ceramic powder and can therefore easily be removed after the component has been coated.
摘要:
In internal coating processes there is often the problem that an outer surface of the component to be coated is also coated. The device according to the invention consists in the fact that the outer surface is protected by a robust outer envelope and a filling material between the component to be coated and the outer envelope.

A belt tensioning device for traction mechanisms includes a receiving and mounting housing, a pulley carrier pivotally connected to the receiving and mounting housing, a bearing supporting the pulley carrier relative to the receiving and mounting housing, and a spring located between the pulley carrier and the receiving and mounting housing for applying the tensioning force. The belt tensioning device, in normal operation, on the slack side between a generator and a main pulley can also be used when the slack side becomes the load side by a blocking mechanism which enables swinging motion of the pulley carrier relative to the receiving and mounting housing in a first direction, and limits or prevents such motion in a second, opposite direction.
