| Description | New Models have been developed for the climb of multiple dislocations that are suitable for use in discrete dislocation simulations. New models have been developed for the sintering of thermal barrier coatings. These have been used to predict desintering and mudcracking in ebPVD coatings |
| Exploitation Route | Our research on thermal barrier coatings can be used to help predict the life of existing coatings used to protect turbine blades and other components that experience high in-service temperatures. They can also be used to aid the development of the next generation of coatings, which will allow higher turbine inlet temperatures to be used, thus improving the efficiency of the turbine. Our models of dislocation climb can be used to provide new insights into the creep deformation of engineering ma |
