Surface Engineering and Nanotechnology Institute

Experts in Surface Engineering and Nanotechnology

The Surface Engineering and Nanotechnology Institute (SENTi) performs world-class research and technological development through engagement with industry. It provides the critical mass of research staff and coating technologies to develop new surface engineering technologies, methods and practice through to prototype component manufacture.

The Surface Engineering and Nanotechnology Institute (SENTi) is a world-leading centre of excellence for innovative research into atomistic and particulate based manufacturing techniques for the production of protective and active surface coating systems with a mission to transform innovative manufacturing research into engineered products.

The Institute works closely with industry, non-government organisations and government agencies to foster the use of coating systems and surface engineering as part of high-value manufacturing and operates across a range of sectors, including aerospace, automotive, oil and gas, biomedical and mining with our client base varying from large multinational companies such as Rolls-Royce and Siemens to SMEs and micro-companies. This ensures that the research carried out, whether at a fundamental, strategic or applied level, is of direct relevance to both industry and academia and demonstrates best surface engineering practice.

SENTi fosters and accelerates development of emerging high value products through fundamental, strategic and applied research from the nanotechnology scale through to prototype component manufacture and integrates this knowledge base into related postgraduate studies.

  • Supporting your business

    Our research is focused at four technology levels:

    • New knowledge, skills and technology (TRL 1-2) - Research and development at this level is undertaken using sponsored research student programmes at Masters and PhD/EngD levels with studentships provided directly by industry, through CASE awards or through government doctoral training account (DTA) programmes.
    • Exploratory studies (TRL 2-3) - Short-term research consultancy contracts, usually 12 months or less, to explore the manufacturing feasibility or early system performance of new materials or coatings.
    • Development of optimised manufacturing methods and coating systems performance validation (TRL 2-4) - Research undertaken by post-doctoral fellows, research staff and established, experienced technical teams. Often research funded at this technology level may be supported by EPSRC, the Technology Strategy Board (TSB), the European Commission and Industry. Programmes can be co-funded or directly funded by industry as required.
    • Pilot scale component manufacture and in-plant performance evaluation (TRL 4-5) - Customer oriented research aimed at new product introduction where batches of components are manufactured at a pre-production pilot scale. Research and development at this level is designed to complement the remit of the TSB HVM Catapult Centres and will usually involve an OEM and their supply chain to provide the necessary manufacturing data to ensure rapid product replacement/insertion into the supply chain. Research is either directly funded by industry or in conjunction with the TSB or European Commission.

    In addition to these four technology driven themes, studentships are available to undertake exploratory science that underpins coating manufacture and surface engineering, independent of any industrial sponsor. Likewise, it is possible to undertake 'commercial in confidence' consultancy directly for industry without the association with postgraduate student training.

  • Our facilities and resources

    The extensive research facilities are incorporated in three Centres of Excellence within SENTi:

    The National High Temperature Surface Engineering Centre (NHTSEC)

    The Centre has established a worldwide reputation for its expertise in designing, testing and analysing coatings/surface treatments, especially for components subjected to extreme and hostile environments. The NHTSEC is a unique university centre - it is 82% funded directly from industrially related contracts and is the only university centre worldwide that can deposit coatings that go directly into Rolls-Royce UK test engines. The Centre has experience and expertise in a range of coating techniques and can be called upon for surface engineering solutions from design of coatings through production, analysis and testing to lifeing of coating systems.

    Sol-gel Coating

    Sol-gel processing is one of the versatile wet chemical methods that can create nano-crystalline or nano-scaled amorphous materials, from oxides in early days to non-oxides in recent times. Sol-gel processing can make organic and inorganic hybrid that bring synergy between the dissimilar properties of organic and inorganic compounds in a single material. Sol-gel processing can lead to the generation of:

    • Dense ceramic bodies
    • Coating/thin films
    • Aerogels
    • Monoliths
    • Ceramic fibres.

    Sol-gel Coating Centre at Cranfield established in late 20th century is equipped with state-of-arts facilities for pilot scale demonstration of all associated operations of the coating technology. The Centre has been working with many industrial partners for development and demonstration of sol-gel coatings for a wide variety of applications, such as, functional coatings/thin films, coatings for antifouling, thermal barrier, corrosion, etc.
