This image shows different coating layers after heating for a certain time. These layers are marked by lines. By calculating the distance between this lines, the thickness of the layers can be determined.
Description: The concept of the novel approach to protection of surfaces is a coating consisting in its initial state of nano- and/or micro-scaled metal particles with a defined size, deposited by spraying, brushing, dipping or sol-gel. During the heat treatment, the binder is expelled, bonding to the substrate surface achieved, the metallic particles sinter and oxidise completely resulting in hollow oxide spheres that form a quasifoam structure. Simultaneously, a diffusion layer is formed below the coating serving as a corrosion protection layer and as a bond coat for the top layer. The structure of the coating system shall be adjusted by parameters like selection of source metal/alloy, particle size, substrate, binder and a defined heat treatment. For fire protection the formation of hollow oxide spheres will be processed in a separate step before deposition.
The flexibility of the new coatings integrates a wide field of application areas, such as gas and steam turbines in electric power generation and aero-engines, combustion chambers, boilers, steam generators and super-heaters, waste incineration, fire protection of composite materials in construction as well as reactors in chemical and petrochemical industry. A broad impact will thus be ensured increasing safety and the durability of components by an economic, multifunctional and flexible protection of their surfaces. The novelty will provide a real step change in the understanding of materials degradation mechanisms in extreme environments.

R-Tech Specific Role: R-Tech performs the qualitative risk assessment in the project and create data base with the coating parameters. Uncertainty in material characterization and modeling and its impact to later implementation, both in regard to technical aspects as well as in regard to social aspects, is another main tasks of R-Tech.
R-Tech is developing the Life Cycle Assessment (LCA) of the new Particoat coating for a specific target application and comparing it with traditional coatings processes like Chemical Vapor Deposition and Pack Aluminizing.
