Method for the surface peening of a component

Abstract

The present technology relates generally to a method for surface peening, particularly shot peening, of a component, particularly a gas turbine component, in which peening bodies, particularly peening bodies designed as balls, are directed onto a surface of a component being peened, in order to machine or strengthen the surface of the component. According to certain embodiments of the present technology, the temperature and / or the velocity of the peening bodies is measured to establish process control of surface peening.

AI Technical Summary

Benefits of technology

[0009]The presently described technology proposes the novel technique of measuring the temperature and / or velocity of the peening bodies during the surface peening process, thereby establishing enhanced control of the surface peening process. The techniques of the present technology can provide for conclusions to be drawn directly and online during processing regarding the quality of surface strengthening that is achieved, for example, during the surface peening process.

[0010]Certain embodiments provide for measurement of the temperature and velocity of the peening bodies, as well as the surface temperature of the component being peened, thereby allowing the surface peening process to be better controlled and / or regulated accordingly.

Problems solved by technology

Gas turbine components, like components of aircraft engines, are subject to high stress loads during operation that can lead to wear and failure of components.

During ultrasonic shot peening using a sonotrode, the operating voltage and / or the operating current of the sonotrode can be measured to monitor and / or control the peening process, but it does not provide direct monitoring of the strengthening of the surface itself.

In particular, no information concerning the mechanical and thermal states of the surface being strengthened can be obtained online during the peening process.
