Materials characterisation

We have the facilities and the expertise required to characterise, record and measure the current condition of your materials or components.

Talk to us about materials characterisation

How we characterise materials

We can record the condition of a sample either destructively or non-destructively. This could be a used component or a material test item. We offer this service either as a stand-alone package or in support of testing and larger investigations.

Our specialist techniques strengthen test results by providing you with further key information – either numerical or interpretative. Recent examples include measuring surface roughness before and after erosion testing and producing a cross-section of a coating to confirm the degradation mechanism.

Metallographic preparation of samples

  • Metallographic preparation including etching

    Sample preparation includes polished or etched embedded sections.

  • Photography

    Samples can be recorded to detail current condition using our photography suite.

  • Optical and scanning electron microscopy

    Microscopy services are available with digital image recording including macroscopy, light microscopy, and scanning electron microscopy (SEM).

  • Positive material identification

    The SEM can also be used to identify materials using Energy Dispersive X-ray (SEM/EDX) Spectroscopy.

  • 2D profilometry

    2D contact surface profilometry is carried out using a Form Talysurf-120L providing information on surface roughness, a wear scar or just surface condition.

  • 3D profilometry

    3D non-contact approaches are available using Alicona Infinite Focus 3D.

  • Computed tomography

    Our ability to record and examine the internal structure of a component non-destructively is a key tool in failure investigations. nC² can access the micro-computed tomography (μCT) facilities of the μ-VIS X-Ray Imaging Centre of the University of Southampton. Our cutting-edge research for our clients has been presented at the International Conference on Engineering Failure Analysis.

  • Micro and nano hardness profiling

    Hardness testing can be carried out using our micro hardness or Vickers hardness testing test rigs.
