PARTICOAT

Raising the operating temperature is mostly the essential key parameter for achieving a higher efficiency of energy conversion as well as a reduction of pollutants and CO2 emission in practically all processes running at high temperatures. Several research programs, like the COST Action 522 for example, were dedicated to this matter. Efficient protection of components at high temperatures against aggressive environments can only be achieved by coating systems. Higher operating temperatures mostly lead the existing coatings to their limits and imply the demand for more advanced coating systems.

The overall objective of the project is to develop a novel, unconventional and cost efficient type of multipurpose high temperature coating systems on the basis of property tailoring by particle size processing of metallic source materials. The novel type of coating shall offer a new alternative for wide industrial applications. It shall possess multi-functionality and integrate a wide field of application areas, such as gas and steam turbines in electric power generation, aeroengines, combustion chambers, boilers, steam generators and super heaters, waste incineration, fire protection of composite materials in construction as well as reformers and reactors in chemical and petrochemical industry. The multi-functionality  comprises thermal barrier effect, oxidation and corrosion protection, lotus effect, electrical insulation at elevated temperatures and fire protection.

►Easy to apply
►Low cost
►Low application temperatures
►Possibility to form dense layers with increased mechanical compliance
►Alumina is no oxygen conductor and provides a very good barrier effect against ingress of corrosive species
►Significant potential for electrical and thermal insulation
►Al subsurface reservoir for protective alumina scale formation

Steinbeis Advanced Risk Technologies (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.

In addition, 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. The current LCA is bases on methodology stated on ISO 14040 and ISO 14044, which consist of four steps:

1. Goal & Scope definition
2. Inventory Analysis
3. Impact assessment
4. Interpretation
