Definitions
- the invention relates to a method for surface blasting, in particular for shot peening, of a component, in particular of a gas turbine component, according to the preamble of claim 1.
- Gas turbine components such as components of aircraft engines
- all optimization potential must be exploited.
- This also includes an optimized utilization of the potentials of materials from which the components are made.
- the surfaces of the components are of particular importance, since the surfaces or edge layers are exposed to maximum stress during operation.
- the surfaces or edge layers usually form the starting point for the failure of a component.
- the surface hardening of components is preferably carried out by shot peening.
- shot peening balls are accelerated with compressed air, by means of a blast wheel or by means of a sonotrode oscillating in the ultrasonic frequency range and directed to a surface of a component to be solidified.
- the balls which are accelerated, for example, with the aid of the sonotrode, strike the surface of the component to be solidified in the sense of a statistical distribution and thus bring about a solidification of the component on the surface to be solidified.
- the energy provided by a sonotrode is thus transmitted indirectly or indirectly via the spheres to the surface to be solidified of the component to be irradiated during shot peening.
- the operating voltage is used for process monitoring or process control according to existing practice and / or the operating current of the sonotrode measured, but hereby no direct monitoring of surface hardening is possible. In particular, no information about the mechanical and thermal states of the surface to be solidified can be obtained online therefrom.
- the present invention is based on the problem to provide a novel method for surface blasting of a component.
- the temperature and the speed of the jet body and, in addition, the temperature of the surface of the component to be radiated are measured, the surface radiation being controlled or regulated as a function thereof.
- the present invention relates to a method for surface blasting, in particular for shot peening, of a component, in particular of a gas turbine component. Subsequently, it shall be assumed that the surface blasting is carried out as ultrasonic shot peening, in which case blasting bodies are conveyed with the aid of an ultrasound beam. Accelerated frequency-vibrating sonotrode and be directed to a surface to be solidified of a component to be radiated.
- the speed of the same is measured adjacent to the surface of the component to be radiated, which is the impact speed or rebound speed of the jet body on or from the surface to be solidified of the component to be solidified.
- the temperature of the surface to be radiated is also measured. From these measurements, it is then possible to draw conclusions about the conditions of the surface to be solidified, in particular their thermal and mechanical states, online. As a result, an online process monitoring or online process control of ultrasonic shot peening is possible.
- the measurement of temperatures and velocities is preferably carried out using infrared technology. It should then be noted that boundary walls of a beam space, within which a component to be radiated is arranged, consist of at least partially infrared-transparent material so as to enable the infrared measurement.
