Alloy Stoichiometry and Gas Entrapment Control in Atomized Powders
Controlling melt superheat and nozzle pressure limits vapor pressure elemental loss while helium purge or vacuum degassing eliminates micro-cavity gas voids.
Micro CT
Meaning
High resolution x-ray imaging processes produce three dimensional internal views of an object without physical sectioning. Use of micro ct allows for the inspection of internal battery components at the micrometer scale. It provides a non invasive way to study structural integrity.
Spatial Resolution
Detection of features as small as one micrometer is possible with modern laboratory equipment. While standard medical scanners lack the power for dense industrial samples, micro ct utilizes specialized sources to penetrate metal casings or ceramic structures. This capability reveals cracks and pores that are invisible to the naked eye.
Battery Analysis
Evaluation of electrode health often relies on this technology to track the movement of active materials or the formation of dendrites. A micro ct scan can pinpoint the exact location of a short circuit inside a sealed cell. Researchers use the resulting images to compare the internal state of a battery before and after thousands of cycles.
Data Processing
Reconstructing the raw projections into a digital model requires heavy computational power. Once the micro ct data is processed, software identifies specific phases or defects based on x-ray attenuation differences. This quantitative approach turns visual information into measurable metrics like porosity percentage or particle size distribution.
Modern laboratory units now offer the speed needed for batch inspection in quality control environments.
