Materials Testing

Design Unit: Our Services

Our Materials Laboratories support industrial gear research and consultancy projects in three main areas:

  • metallography and evaluation of material properties
  • heat treatment and grinding quality control
  • characterisation and analysis of gear failures

Our facilities

We use a range of up-to-date laboratory equipment to study the metallurgy of gears and the factors affecting fatigue performance. Our facilities include:

  • sectioning, mounting and polishing equipment for metallographic sample preparation
  • digital imaging and image analysis software connected to stereo and reflected light microscopes
  • micro-Vickers tester for hardness and case depth measurement
  • X-ray diffractometer for measurement of residual stress and retained austenite content
  • Barkhausen Noise analysers for detection of grinding burn
  • scanning electron microscope with EDS capability for fractography and qualitative chemical analysis
  • eddy current crack detection equipment
