Applications for Destructive Material Inspection
Microstructure Analysis
The analysis of microstructural and structural characteristics on a metallographically prepared specimen provides information about the state of tempering and the microstructure, deformation, segregation and contamination. We assess particle sizes and boundaries, porosity, intermetallic phases as well as non-metallic inclusions and phases.
Hardness Testing
Vickers and Brinell hardness testing are among the most important analytical methods for metal components. With our state-of-the-art measuring systems, we determine the hardening depth and the hardness curve reliably. Any embrittlement of the material can also be reliably identified and the possible failure of the component averted.
Weld Seam Inspection
The heat applied during welding can make metals brittle. During weld seam inspection, we prepare, based on several Vickers or Brinell hardness measurements, a hardness curve for the heat-affected zone of the item inspected, check the weld seam geometry and undertake a comprehensive microstructure analysis.
Solder Seam Inspection
Solder seams are assessed in accordance with the standards for compliance with existing tolerances and evaluation groups. Surface irregularities are assessed based on a visual inspection and internal solder seam defects are evaluated using a metallographically polished specimen so that weak spots are identified reliably and can be avoided in future.
Corrosion
With the aid of damage analytical methods, we analyse a very wide range of corrosion types and show you possible causes. Our experts have the necessary detailed knowledge of the related application to be able to analyse corrosion behaviour and evaluate the behaviour of the material in its surroundings.
Material Identification
For the identification of unknown materials and inclusions in samples and components, we use various reliable, practically-proven methods to be able to provide you with a reliable result. During EDX analysis, material identification at the elementary level is also possible using a scanning electron microscope.
Surface Roughness
Using a laser scanning microscope, we analyse without contact the surface roughness and topography of metals, polymers, semiconductors, ceramics, multiple coating systems and much more. We can then evaluate the quality and functionality of the surfaces as well as any material wear or cavities and depict our findings in three dimensions.
Coatings
For the analysis of protective and function-related coatings, we use numerous analytical techniques to determine the coating thickness, the fusion line, the surface topography, the roughness, the microhardness and much more. It is also possible to evaluate the surface of the coating and to determine the material composition of the coating.
Layer Thickness Measurement
Layer thickness measurement on composite polymers can also be undertaken using a laser scanning microscope with a resolution in the range of a few nanometres. The reliable and highly accurate three-dimensional depiction of the individual layers of the related workpiece is also possible using this proven analytical method.
Scanning Electron Microscopy
Scanning electron microscopy permits the high-resolution and three-dimensional depiction of surfaces and structures as well as the determination of the chemical composition of the sample (EDX analysis). FIB-SEM microscopy makes possible sample preparation in nanoscale for the in-depth analysis of microstructures and coatings.
Tensile / Compressive / Bending Testing
Tensile, compressive and bending testing form part of the classic repertoire of destructive material testing. With modern test equipment, comprehensive knowledge of the relevant standards and extensive practical experience, our experts ensure the individual tests are undertaken correctly.
Alloy Composition (OES)
Using spark emission spectroscopy (OES) we analyse individual alloy elements such as iron, aluminium, copper, zinc, magnesium, titanium, cobalt or nickel both qualitatively and quantitatively for their composition. These results are compared with the limits listed in the standards and the steel code or your specific requirements and evaluated.

Application Areas of Destructive Material Inspection
Whether steel, aluminium, ceramic or plastic: all materials are subject to signs of wear or can have manufacturing-related defects. With the aid of destructive material inspection, we identify undesirable anomalies and damage in components and parts and give you the necessary knowledge to rectify expensive sources of defects. Customers from numerous industrial sectors trust in our expertise.
Electronics Manufacturing
In the field of microelectronics and semiconductors, we analyze assembled and unassembled printed circuit boards (PBA/PCBA) in accordance with IPC standards, examine the delicate coating systems of electronic components, and assess the material composition and quality of solder joints and microstructures.
Methods such as cross-section analysis, SEM-EDX, 2D/3D CT, or the dye-and-pry test enable precise failure analysis for delaminations, contact failures, ionic residues, and failures of electronic assemblies.
Battery Cell Analysis
Materialographic analyses ensure the quality, safety, and performance of modern battery systems. These analyses examine raw materials, layer structures, structural defects, contamination, and safety-critical damage such as delamination or dendrite formation.
Methods such as micrographic analysis, SEM/EDX, FIB-SEM, and 2D/3D CT enable quality control of battery systems as well as the precise examination of failed batteries (post-mortem analyses) to optimize manufacturing processes and service life.
Security & Defence
In the security and defense industries, materials testing and materialography ensure the safety, reliability, and quality of critical systems. Tests are conducted on material integrity, welds and coatings, contamination, electronics, and the structural and component strength.
Methods such as materialography, SEM-EDX, X-ray/CT analysis, and residual contamination analysis help detect defects early, minimize the risk of failure, and ensure reliable compliance with standards and documentation requirements.
Medical Technology
It is crucial that the inner walls of stents and other medical products to be placed in the human body have an absolutely smooth surface to prevent the formation of clots and other life-threatening complications.
Scanning electron microscopy permits not only the checking of the surface roughness and general characterisation of the surface topography, it also permits verification of adhering contamination.
Automotive
For the automotive sector, we provide numerous services in the area of destructive material inspection. Along with the microscopic inspection of component surfaces, hardness testing and hardness curve testing are particularly important.
We analyse the causes of corrosion as well as the causes of fractures and other physical damage to the material. In addition, we use various methods for the characterisation of signs of wear and surface anomalies.

Frequently Asked Questions about Destructive Material Inspection
During destructive material inspection, the selected materials are checked for their chemical and physical characteristics. Destructive inspection includes, e.g. microstructure analysis, spark emission spectroscopy, various tensile/compressive and bending tests, as well as torsion testing or notch impact testing.
IYes, during destructive material inspection the components inspected are, as a rule, changed so significantly or completely destroyed that they can no longer be used afterwards. An exception may be Vickers or Brinell hardness testing. The indenters used in these methods only damage the surface of the component slightly such that it may still be possible to use, in particular, larger components. For this reason these methods are often termed conditionally non-destructive material inspection.
During non-destructive material inspection, the component is checked in a manner that does not permanently change or damage the material. It can therefore be used completely normally after the testing. Non-destructive inspection methods include 2D X-ray inspection and 3D-computed tomography, the tactile metrology and optical metrology, as well as eddy current inspection or visual inspection.
