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- and macro-Vickers testers for hardness and case depth measurement
- X-ray diffraction equipment for measurement of residual stress and retained austenite
- Barkhausen Noise analysis for detection of grinding burn
- a scanning electron microscope with EDS capability for fractography and qualitative chemical analysis
- eddy current crack detection equipment
