SOFC Protection Coatings Based on a Cost-Effective Aluminization Process

Performer: NexTech Materials Ltd.

Project No: SC0008203

Project Scope and Technology Readiness Level

Under this Phase II SBIR award, researchers at NexTech Materials, Ltd. are developing coatings for metallic SOFC interconnects and balance of plant (BOP) components using a cost-effective aluminization process. In Phase I, NexTech, Ltd. demonstrated that low cost coatings for SOFC interconnects are available that meet the needs of SOFC developers. In Phase II, NexTech is performing critical process development in parallel with cost and manufacturing analyses to accelerate the demonstration of these coatings in concert with end-user evaluations.

The project will focus on Aerosol Spray Deposition (ASD) - a low cost, high-volume manufacturing process for providing metallic components with protective aluminide diffusion coatings. Requirements and specifications for the coating technology for these SOFC applications will be solicited from SOFC developers at the commencement of the project and this information will be used throughout the remainder of the project to ensure coating development is commercially focused and relevant to industrial needs. NexTech will demonstrate the commercial viability of the proposed aluminization process to provide an aluminide diffusion coating for the non-active, seal area of dual-coating metallic interconnects and as a BOP protection coating. Tasks are therefore arranged so that these two goals can be pursued in parallel paths once a down-selected aluminization process has been identified.

The Technology Readiness Level (TRL) assessment identifies the current state of readiness of the key technologies being developed under the DOE’s Clean Coal Research Program. In FY 12, this project was not assessed.

The TRL assessment process and its results including definition and description of the levels may be found in the "2012 Technology Readiness Assessment-Analysis of Active Research Portfolio".
