Materialenanalyse

Materialenanalyse is the systematic investigation of materials to determine their composition, structure, properties, and performance. It is an interdisciplinary field that combines principles from physics, chemistry, and engineering to support material development, quality assurance, and failure analysis. The practice encompasses both non-destructive and destructive methods, selected according to the objectives, material type, and the level of detail required.

Non-destructive techniques include X-ray fluorescence (XRF) for elemental composition, X-ray diffraction (XRD) for crystalline phases, infrared and Raman spectroscopy for molecular structure, and imaging methods such as optical microscopy and scanning electron microscopy (SEM). SEM often integrates energy-dispersive X-ray spectroscopy (EDS) for local composition. Additional non-destructive tools cover ultrasonic testing, radiography, and surface analysis methods complemented by profilometry or tribology studies. Destructive analyses provide deeper microstructural and chemical insight and may include metallography with etching, SEM/EDS/EPMA, transmission electron microscopy (TEM), and chemical analyses such as inductively coupled plasma mass spectrometry (ICP-MS) or chromatographic techniques.

The analysis process typically involves careful sample preparation, measurement, data interpretation, and reporting, with attention to accuracy, traceability, and uncertainty assessment. Standards from bodies such as ISO and ASTM guide calibration, method validation, and quality control.

Applications extend across quality assurance in manufacturing, materials selection, failure analysis, forensic investigations, and research and development. They cover metals, polymers, ceramics, composites, and coatings, and encompass subfields like metallography, polymer analysis, ceramic analysis, and surface and corrosion studies.
