METHOD AND DEVICE FOR ASCERTAINING AN EDGE LAYER CHARACTERISTIC OF A COMPONENT

摘要

The invention relates to a method and device for ascertaining an edge layer characteristic of a component (12), in particular a component (12) for an aircraft engine. In the method according to the invention, a reference body (22) with a known edge layer characteristic is arranged on the surface of the component (12). At least one ultrasonic wave (18) is introduced into the surfaces of the component (12) and the reference object (22) by means of an ultrasonic transmitter (16). At least one ultrasonic wave (18) resulting from the exchange between the component (12) and the reference body (22) is detected by means of an ultrasonic detector (20), and an edge layer characteristic of the component (12) is ascertained by means of an ascertaining device (28) using a difference between the at least one generated ultrasonic wave (18) and the at least one resulting ultrasonic wave (18).

1. A method for ascertaining an edge layer characteristic of a component (12) for an aircraft engine, comprising the steps of:
disposing a reference object (22) with a known edge layer characteristic on the surface of the component (12); introducing at least one ultrasonic wave (18) into the surfaces of the component (12) and the reference object (22) by means of an ultrasonic transmitter (16); detecting at least one ultrasonic wave (18) resulting from the interaction with the component (12) and the reference object (22) by means of an ultrasonic detector (20); and ascertaining an edge layer characteristic of the component (12) by means of an ascertaining device (28), based on a difference between the at least one ultrasonic wave (18) that is generated and the at least one ultrasonic wave (18) that results.
