摘要:
The invention relates to a method for repairing components (1) comprising a base material with an oriented microstructure, wherein the repair point (3) comprises a correspondingly oriented microstructure as the surrounding base material. According to the inventive method, solder (7) is applied in the region of a point (3) which is to be repaired and is soldered to the component (1) by means of a heating effect produced by a device (9). A temperature gradient, i.e, approximately a temperature characteristic, is produced during the heating effect, said temperature characteristic ranging from a high to a low temperature in the region of the point (3) which is to be repaired.

Plastics do not have the mechanical or erosive properties required for specific areas of application. The inventive plastic comprising powder particles (7) improves the properties of said plastic in relation to mechanical characteristics and erosive properties for components, coatings and sealing systems.

In prior art, electrolytic methods are used for processing large exterior surfaces. According to the inventive method, through holes (7, 7', 7'', 7''', 7'''', 7''''') of a wall (4) are treated on the inside, one respective pole electrode (19, 19', 19'', 19''') being assigned to each through hole (7, 7', 7'', 7''') that is to be processed.

Operationally-stressed components are often returned to use by means of an acid treatment. The duration during which the component remains in the acid is conventionally fixed at a standard value, such that individual stresses are not taken into account. According to the invention, layers may be removed from a component whereby a voltage is at least repeatedly applied to the component, causing a current (I) to flow, the time course of which represents the status of the process of layer removal and which is used to decide the ending or interruption of the acid treatment.

According to the prior art, electrolytic methods comprise pulsed currents or voltages that have the same voltage level over time. According to the invention, pulsed currents or voltages (U) are likewise used, but the level of the pulse amplitude of the voltage (U) or of the current either decreases or increases with time (t).
摘要:
Protective layers, according to the prior art, achieve their protective function by depletion of a defined element that forms a protective oxide layer or that is exhausted as a sacrificial material. Once said material is exhausted, the protective function cannot be maintained. The invention is characterized by using particles (1) that contain a sustained-release depot of the exhaustible material. For this purpose, the material is present in a superstoichiometric form.

The invention relates to a method for integrally bonding parts to be joined (1, 7) that comprise joint areas. Said method consists of the following steps: the joint areas of the parts to be joined (1, 7) are placed together; nanoscalar particles that form a particulate material (11) are introduced into the joint gap (9) between the joint areas; and the particulate material is melted and then re-solidified.
