A method for producing or repair of turbines - or motor, as well as component, namely turbines - or engine component

摘要

The invention relates to a method for producing or repair of monocrystalline turbines - or triebwersbauteilen, wherein a solder is heated to a temperature which is greater than or equal to the melting temperature of this solder is. Subsequently, the resulting melt the solder in a in the turbines - or engine component tearing, or formed into a between two turbines - or gap formed components introduced. Subsequently, the temperature of the solder during a epititaktischen solidification process of this solder controlled not - isothermally. This process, which is, for example, in conjunction with turbines - or engine components made of a nickel based alloy - - can be applied, has, compared with conventional method the advantage that it, in particular in the case of large gap - or crack widths, a more rapid soldering repair of turbines - or components and, moreover, makes it possible with this method can be effected, that the repaired regions again a single-crystal structure and therefore the corresponding high mechanical strength, resistance to oxidation and have re-melting temperature.
