Surface Engineering & Precision Institute

The future in Materials and Manufacturing is where science, technology and design collide. Cranfield’s Surface Engineering and Precision Institute (SEPi) is a world-leading centre that brings together scientific and engineering disciplines, integrating materials characterisation, design and manufacturing expertise to enable the manufacture of future smart systems, sensors and coatings through the discovery/development of materials with purpose-built properties.

The Surface Engineering and Precision institute (SEPi) at Cranfield University is an internationally recognised centre of excellence in material research and development. Its research covers two main specialisms: Coating/Surface Engineering and Device/Smart Materials; both aiming to undertake world-leading research in the areas of materials engineering and functional materials.

Each specialism is supported through distinct organisational structures based on research groups with particular disciplinary expertise (e.g. polymers, nanotechnology), and research themes (e.g. biomedical, high temperature corrosion and protection), which facilitate cross-disciplinary interaction between groups, other schools, research institutes in the University, and external organisations.

These cross-domain groups deliver on our strategy of opening the door to new technologies, whether they are in sustainable, aeronautical, biomedical, or sensor engineering. SEPi’s vision is supported by fundamental and applied research that aims at addressing challenging material engineering problems facing the world and providing translational and sustainable solutions as explained by Dr. Gregory Bizarri, acting Head of the centre.

Surface coatings

 “Our main research activities relate to the design and manufacture of protective coatings to allow engineering systems to operate in harsher and more demanding environments. Here, research is focused on the design and manufacture of Thermal Barrier Coatings, High temperature corrosion resistant coatings and the development of in-situ diagnostics (Smart Coatings), as well as and the design of surface engineering solutions at the systems level,” he says.

High Temperature Corrosion and Mechanical Interactions

 “Our approach encompasses the assessment of materials performance in a variety of aggressive environments from all aspects of industry from the aero-gas turbine to boiler plant to concentrating solar power plant. Not only do we offer a testing solution, within the centre we are able to offer solutions to engineer materials performance through in-house coating solutions.”

Sensors and devices

 “Our research focuses on providing solutions for sensing devices, functional materials and their integration at system level. We have a speciality in advanced functional materials such as piezoelectric, pyrolelectric, thermoelectric, catalytic, luminescence, radiation detectors and biosensors working at the nano to micro and macro scales. This effort greatly benefits from our expertise in ultra-precision engineering that allows rapid and fine feature generation processes for multi-scale processing and effective quality control.”
