    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, a reference body (22) with a known edge layer characteristic is arranged on the surface of the component (12). An ultrasonic wave (18) is introduced into the surfaces of the component (12) and the reference object (22) by an ultrasonic transmitter (16). An ultrasonic wave (18) resulting from the exchange between the component (12) and the reference body (22) is detected by an ultrasonic detector (20), and an edge layer characteristic of the component (12) is ascertained by an ascertaining device (28) using a difference between the generated ultrasonic wave (18) and the resulting ultrasonic wave (18).

    摘要： Disclosed is a method for the non-destructive testing of workpiece surfaces of a workpiece by means of fluorescent penetrant testing or dye penetrant testing. The method comprises applying a penetrant to the region of the workpiece surface to be examined, thereby allowing the penetrant to penetrate into possible recesses in the workpiece surface, applying a developer to the region of the workpiece surface to be tested; bleaching the penetrant by a gaseous or liquid oxidant; and visually assessing the penetrant that has remained in the recesses present in the workpiece surface.

    摘要： A method for determining residual stresses of a component (14), in particular a component of an aircraft engine, while it is being manufactured by an additive manufacturing process. The method includes the following steps: creating at least one local melt pool (26) in a surface (24) of the component (14) to be manufactured after a predetermined portion of the component is completed; optically detecting surface distortions and/or elongations occurring at least in a region around the created melt pool (26); and determining the residual stresses of the component (14) which are present at least in the region around the created melt pool (26) based on the optically detected surface distortions and/or elongations. Further an apparatus for determining residual stresses of a component (14) while it is being manufactured by an additive manufacturing process is provided.
