Improving the Efficiency and Quality of Sustainable Industrial CT by Optimizing Scanning Parameters

Sensors, Год журнала: 2025, Номер 25(8), С. 2440 - 2440

Опубликована: Апрель 12, 2025

Industrial Computed Tomography (CT) is a widely used Non-Destructive Testing (NDT) technique for evaluating internal and external geometries with high accuracy. However, its integration into industrial workflows often hindered by long scan times energy consumption, raising sustainability concerns. This study introduces novel approach to improving CT efficiency integrating real-time consumption monitoring the scanning process. A power measurement device was correlate parameters usage image quality, enabling data-driven parameter optimization. Results show that higher voltages improve quality up 32%, when evaluated using Contrast-to-Noise Ratio (CNR) amongst other metrics, while reducing overall 61%. The results presented support optimization of providing quantitative guidelines balance efficiency, sustainability. Additionally, deviations in dimensional measurements obtained through scans were compared against reference data from Coordinate Measuring Machine (CMM), differences ±45 μm. findings contribute enhancing performance minimizing environmental impact.

Design and Additive Manufacturing of TPMS Heat Exchangers

Applied Sciences, Год журнала: 2024, Номер 14(10), С. 3970 - 3970

Опубликована: Май 7, 2024

Triply periodic minimal surface (TPMS) heat exchangers (HXs) have been investigated in this paper along with additive manufacturing (AM). Heat transfer coefficients, pressure drops, and thermal capacity were systematically evaluated as functions of wall thickness, lattice cell density, materials. It turns out that when conductivity is above 100 W/m·K, gyroid HXs are less sensitive to variations thickness conductivity. Additive 20 kW aluminum was successful testing results comparable theoretical prediction. To the best our knowledge, first demonstration a working prototype TPMS HXs.

Nanostructuring of Additively Manufactured 316L Stainless Steel Using High-Pressure Torsion Technique: An X-ray Line Profile Analysis Study

Materials, Год журнала: 2024, Номер 17(2), С. 454 - 454

Опубликована: Янв. 18, 2024

Experiments were conducted to reveal the nanostructure evolution in additively manufactured (AMed) 316L stainless steel due severe plastic deformation (SPD). SPD-processing was carried out using high-pressure torsion (HPT) technique. HPT performed on four different states of 316L: as-built material and specimens heat-treated at 400, 800 1100 °C after AM-processing. The motivation for extension this research annealed is that heat treatment a usual step 3D printing order reduce internal stresses formed during studied by X-ray line profile analysis (XLPA), which completed crystallographic texture measurements. It found sample contained considerable density dislocations (1015 m-2), decreased about half original treatments °C. hardness varied accordingly annealing. Despite difference caused annealing, processing led similar microstructure increasing strain samples with without saturation values crystallite size, dislocation twin fault probability 20 nm, 3 × 1016 m-2 3%, respectively, while maximum achievable ~6000 MPa. initial <100> <110> textures changed <111> processing.
