A consortium of four research centres is pooling their equipment and expertise to create a national "Innovation Playground" for developing advanced protective coatings that reduce friction and wear on metal surfaces. These coatings, applied using a technique called Physical Vapour Deposition (PVD), are currently limited in how well they perform under extreme conditions. The problem is that many critical components—from artificial hip joints to car engines to cutting tools for aerospace manufacturing—fail prematurely because their surfaces degrade under high loads, temperatures, or chemical attack. The consortium will focus on three specific sectors where current coatings fall short. If successful, the research could deliver longer-lasting artificial joints that release fewer metal ions, allowing younger, more active patients to avoid revision surgery and reducing the burden on the NHS. In automotive engines, better coatings could cut friction, improving fuel economy and lowering carbon emissions. For manufacturing, tougher coatings that withstand temperatures above 1000°C would allow dry machining of titanium and carbon-fibre composites, eliminating the need for chlorine-based cutting fluids and reducing energy use. The investment in capital equipment will give the UK a unique capability that other academic groups and industrial users can also access.

A team with unique and complementary experience has been formed to create an Innovation Playground for application-driven pioneering research in PVD coatings for tribological applications. Four leading centres in three institutions will come together to exploit their real and significant synergies. This proposal is for capital equipment which, together with our extensive existing facilities, will underpin our ambitions and will enable the UK to compete with any of the other international centres. The investment provides unique capability for this consortium which will reach out to other academic groups and industrial users. The proposed research is based around three core thematic areas; defined because of our combined strengths in these and also the tribological challenges that exist. The Innovation Playground will secure specific deliverables for these three strategically important high priority application sectors:1. Artificial Human Joint Replacements - for health & well being -> Lengthening life, improving mobility and independent living and reducing ion release for younger and more active patients. To reduce the burden on the NHS. 2. Automotive OEM Engine Parts - for reduced energy consumption - The immediate focus is primarily on fuel economy and improved surface/lubricant interactions to realize lower interfacial friction and so minimize energy losses, delivering performance improvements and a reduced carbon footprint.3. New age coated cutting tools for Manufacturing Ti, Carbon Fibre Reinforced Polymer (CFRP) and metal-matrix composite aerospace components - for materials conservation and manufacturing efficiency gains by lowering energy consumption in manufacturing > The main emphasis will be increasing cutting tool durability and reliability under very high operating temperatures (>1000C), suppressing adverse chemical degradation and reducing dependence on Cl-containing fluids during machining operations under dry or minimum lubrication conditions (MLC machining). There is industry pressure to increase the performance of the tool/lubricant system and advanced PVD coating technology can address this need.
