Modern production processes including hot isostatic pressing (HIP), additive manufacturing and metal injection molding and manufacturing techniques involving metal powders.
Micro-CT is used to determine the morphometry of particles in powder metallurgy, for demanding production processes. As a non-destructive technique, it’s also extremely useful for looking inside objects in failure analysis and final parts inspection.
Characterise samples from µm to cm scale in minutes
Applications
Micro-CT is widely used in areas including:
CAD Comparison
Compare manufactured parts with CAD models.
- Measure deviations in 3D, on both internal and external surfaces
- Set pass/fail tolerances at pre-defined inspection points
Parts Inspection
- Examine failed products
- Analyse cracks and voids
- Check contact areas at interfaces
- Investigate defects
- Examine reactions to stress and temperature with in-situ stages
Morphometry
Quantitative determination of :
- Porosity & inclusions
- Volume fractions
- Orientation
- Dimensions
- Surface
- Angles
Metal Powders
Quantitative analysis of metal powders – measure parameters including:
- Sphere size distribution
- Sphericity
- Packing
- Porosity
- Surface to volume ratio
- Surface roughness
- Convexity
- Form factor
