A method is disclosed for providing a component. During this method, braze powder is deposited with a substrate. The braze powder is sintered together during the depositing of the braze powder to provide the substrate with sintered braze material. The sintered braze material is heated to melt the sintered braze material and to diffusion bond the sintered braze material to the substrate to provide braze filler material. A first object is scanned using computed tomography to provide first object scan data. The first object includes the substrate and the braze filler material diffusion bonded to the substrate. The first object scan data is compared to first object reference data to provide machining data. The first object is machined using the machining data to provide a second object.

A method of producing a computer-generated image of a component part includes receiving scan data of the component part. The scan data includes a plurality of slices that change direction about a normal vector. The method further includes registering the scan data of the component part and transforming the scan data of the component part into a set of slices arranged in an x-y plane. Further, the method includes aligning the set of slices aligned along the axis along an axis in the x-y plane. In addition, the method includes adjusting the set of slices aligned along the axis using a background model for the component part, the scan data, or both. Thus, the method includes applying a directional filter to the set of slices aligned along the axis and generating the computer-generated image of the component part using the filtered set of slices aligned along the axis.

A method of CT scanning a plurality of aerofoil blades. The method includes the steps of: providing a rotatable support arranged for rotation about an axis of rotation and within an energy beam; mounting a plurality of aerofoil blades to the support in spaced-apart relationship to one another so as to form at least one array around the axis of rotation; and rotating the support about the axis within the beam. Each blade has an aerofoil section and is mounted to the support such that the span of its aerofoil section is substantially parallel to the axis of rotation, and the blades are arranged such that no line orthogonal to the axis of rotation intersects the aerofoil section of more than one blade.

Each blade has an aerofoil section and is mounted to the support. The method also provides an elongate identification element on the rotatable support, the identification element being arranged such that its longitudinal axis is parallel to the axis of rotation and having a transverse cross-sectional shape along at least part of its. Each edge feature corresponds to and is directed towards a respective said blade to thereby facilitate identification of individual the blades in a CT output obtained via the method.

A method of detecting defects on a surface or interface of a part is provided. The method includes: providing data from an X-ray scan of the part; processing the scan data to obtain an original 3D or 2D model of a surface or interface topology of the part; and filtering the original 3D or 2D model of the surface or interface topology to identify deviations from the expected surface or interface topology of the part. The identified deviations may be produced by surface or interface defects on the part.

There is provided a method for scanning of objects in a scanning apparatus. The method comprises disposing the objects on a support of the scanning apparatus, so that the objects are positioned between an imaging beam emitting element and an imaging beam receiving element oppositely disposed to either side of the support. The support is rotatable relative to the emitting and receiving elements about an axis of rotation to allow creation of an image from projections each taken at a different relative angle of rotation. The objects are positioned adjacent each other on the support in a configuration that reduces the variation in material thickness penetrated at the multiple relative angles of rotation. The method further comprises operating the scanning apparatus at the multiple relative angles of rotation to produce an image of the objects.
