Computed tomography with three-dimensional porosity analysis
Computed tomography with three-dimensional porosity analysis is a method for precise measurement and visualization of pores in castings. It provides detailed information on the volume fractions and location of pores, which is crucial for quality assurance and optimization of the casting process.
Physical-Chemical Mechanism of Action
Computed tomography (CT) images the internal structures of a material through various layer scans. Three-dimensional porosity analysis uses this data to detect pores and determine their size, shape, and location.
Metallurgical Relevance & Risks in Welding
Pores in castings can lead to cracks and deformation. A precise analysis of porosity makes it possible to identify the causes of pore formation and take measures to reduce it. This improves the overall quality of the casting process and reduces the risk of defects.
Workshop Practice & Instructions
To perform computed tomography with three-dimensional porosity analysis, special CT equipment is needed. The procedure involves taking multiple layer scans of the casting and subsequently analyzing the data with appropriate software. The results are presented as 3D visualizations that show the pores visually and quantitatively. This information can then be used to optimize process parameters or take measures to reduce pore formation.
