We provide porosity and inclusion analysis using computed tomography (CT) for the non-destructive detection and evaluation of internal material defects. The method enables reliable inspection of castings and other components without damaging the tested part.
Method
Porosity and inclusion analysis allows defects such as blowholes, pores, bubbles, and inclusions to be detected and analyzed throughout the entire volume of a component. The complete 3D dataset is evaluated, enabling defects to be identified independently of their absolute gray values and subsequently verified through plausibility checks.
Detected pores and inclusions are displayed using color-coded visualization in both 2D and 3D views. Detailed information for each individual defect, including its volume, projected size, and location, is provided in tabulated form.
The analysis can also be performed in accordance with standards defined by the VDG (German Association of Foundry Specialists) and Volkswagen AG. This approach enables fast, non-destructive CT-based defect evaluation and can replace conventional destructive and time-consuming methods based on micrograph analysis.
Equipment
The analysis is carried out using industrial computed tomography (CT) systems and specialized software for three-dimensional defect detection, quantitative evaluation, and visualization of porosity and inclusions throughout the inspected component.
