Tribology and Surface Engineering Laboratory

The Tribology and Surface Engineering Laboratory at AUT is a multidisciplinary lab conducting research in different aspects of tribology. It is the first research lab of its kind in New Zealand.

We have an extensive range of industrial expertise on tribology-related problems that can be provided to New Zealand industry through joint projects, consultancy and problem-solving services.

Tribology: key role in modern and future technology

Tribology plays an important role in almost all aspects of modern technology where one material slides or rubs over another and tribological performance is a crucial factor for engineering design. It is immensely important to the successful operation of engineered machines and natural mechanisms of all scales, and demands multifunctional surfaces.

Tribology is core to future transport and energy-efficient machines, the control of emissions and low-maintenance renewable energy systems, and to biomedical applications. In order to develop advanced components for these applications, it is necessary to understand and control basic friction, wear, and lubrication processes at the sliding interface.

Facilities

The lab is equipped with a range of modern test instruments for tribological and mechanical characterisation. Capabilities range from evaluation for lubricants, fuels and additives to unique friction, wear and tribo-corrosion testing capabilities for advanced materials and surface coatings, specialised tribometers for high temperature testing as well as testing in special environments.

  • Linear reciprocating tribometer (high temperature testing up to 600°C, high sliding speed)
  • Rotary tribometer (high temperature testing up to 800°C, humidity control)
  • Block on ring tribometer
  • Rheometer
  • Electro-chemical corrosion set-up
  • Tribo-corrosion test set-up
  • Micro-scratch tester
  • Macro and micro-indentation testers
  • 3D optical profilometer
  • Stylus profilometer
  • Scanning electron microscope
  • Energy-dispersive x-ray spectroscopy
  • Atomic force microscope
  • Servo-hydraulic testing machine
  • High temperature tensile testing machine
