Description

Technical Field

[0001] This utility model belongs to the field of industrial CT testing technology, and in particular relates to an industrial CT solid-liquid density resolution test sample. Background Technology

[0002] Industrial CT has emerged as a novel non-destructive testing method in recent years. It boasts advantages such as being unaffected by the material type, shape, or structure of the object being inspected. It can clearly, intuitively, and accurately display the internal structure, material composition, and defects of the object in the form of images. Therefore, industrial CT technology is widely used for the qualitative measurement and analysis of material density. However, CT-inspected materials often have high density, a wide range of variations, and complex structures, making accurate quantitative measurement of the inspected workpiece's density difficult. Industrial CT tests solids and liquids separately; however, in practical engineering applications, traditional qualitative measurements are insufficient. Currently, the lack of solid-liquid density resolution test samples leads to disadvantages such as low CT density detection efficiency, high inspection costs, and significant equipment wear and tear.
