Pores

Pores are void spaces present within a material or component. Pores can have varying shapes and sizes and can be formed due to various factors such as material processing, manufacturing methods, or environmental conditions.

Pores can be an indication of potential defects within a component and can compromise its material strength. Hence, it is important to detect and identify pores early on to avoid potential failures or damages.

In CT, pores can be detected using X-rays. The X-rays penetrate the material and are absorbed by the pores, creating a difference in the X-ray transmission between the pores and the surrounding material. This difference is then converted into CT data, which can be visualized in a 3D image of the component.

The size of the pores can also be determined by analyzing the density changes in the CT data. This information is particularly useful in quality control and evaluation of components, as it enables quantification of the size and number of pores and assessment of the suitability of the component for its intended use.

In addition to pore detection, CT can also be used to analyze other defects such as cracks, inhomogeneities, or inclusions. CT thus provides a powerful method for non-destructive inspection and analysis of components, enabling identification of potential defects and improving the quality of materials and products.
