| Description | New methods have been developed to deposit functional and protective ceramic coatings on metal and polymer substrates, at room temperature, using the particulate aerosol deposition process. Modifications were made to the ceramic powder processing procedures and the deposition system to improve the properties of the coatings and reproducibility of the aerosol generation unit. This unique deposition facility, which has been developed within the Henry Royce Institute in Manchester, provides new opportunities to combine conventionally incompatible materials in novel types of composite coatings as a result of its ability to produce dense, cohesive and adherent ceramic coatings at room temperature. In one example, a thin dielectric ceramic coating has been applied on a polymer sheet for high voltage electrical insulation, leading to a 60-fold increase in lifetime under an accelerated partial discharge test procedure. New research collaborations have been initiated to conduct further work on novel types of ceramic coatings for dielectric capacitors, electrically insulating ceramic coatings for electric drive systems in automotive and aerospace applications, protective ceramic coatings to improve corrosion, wear and oxidation resistance of metallic alloys, and modelling and simulation of the particulate aerosol deposition process. |
| Exploitation Route | The developing facility for low-temperature manufacture of ceramic films by particulate aerosol deposition in the Henry Royce Institute at Manchester will support a wide range of research activities on functional and protective coatings. Our initial work on ceramic dielectrics for capacitors has already been expanded to include electrical insulators for metallic conductors, protective coatings for light alloys, and bioactive coatings for implants. There is clear potential to extend the range of applications further to include topics such as hydrogen barrier coatings, ceramic electrolytes for fuel cells and solid state batteries, flexible electronics, abrasion resistant coatings for engineering polymers and other types of composite or multilayer devices incorporating traditionally incompatible materials. Exploitation of the results of this work will be accelerated through collaboration with other research institutes and industries across the UK, supported by the Henry Royce Institute. |

| Description | During this project, we developed a novel combination of ceramic powder processing, involving the high energy ball milling of solid powders followed by granulation by spray-drying, to facilitate the aerosol deposition of high density ceramic coatings at room temperature. It was demonstrated that such dielectric coatings can be used to protect polymeric electrical insulators against erosion by the 'partial discharge' mechanism, resulting in a 60-fold increase in the time to failure during an accelerated lifetime test. These results formed the basis for a collaborative R&D project with aerospaceHV (aHV) through the University of Manchester Impact Acceleration Account Proof of Concept Scheme. We are currently exploring the application of such coatings in high voltage systems for transport and power transmission, and are engaging with various industrial partners ranging from materials and wire manufacturers to end users in the aerospace and automotive sectors. |

| Results and Impact | Dr Yizhe Li and Dr David Hall engaged with Emma Doughty, a Science Writer a Diamond Light Source, to prepare a Science Highlights article for inclusion on the Diamond website. The aim of the article is to highlight some of the results of our experiment conducted on beamline I-15 in 2023, "The origin of ultrahigh electrostrain in Bi0.5Na0.5TiO3-based piezoelectric ceramics" (experiment no. cy311608). The article is focused mostly on the results described in a scientific publication, "Acceptor doping and actuation mechanisms in Sr-doped BiFeO3-BaTiO3 ceramics", published in the Journal of Materiomics in 2024 (DOI:10.1016/j.jmat.2023.04.007), although it also provides insight into the potential usage of such materials as a new type of lead-free piezoelectric component in ultrasonic transducers for condition monitoring in demanding environments. The Research Highlights article has helped to raise the profile of our research activities and contributed to increased citations of this recent publication. |
