A Software Tool to Design Thermal Barrier Coatings

Deformation Control Technology, Inc.

Cleveland, OH

Software that enables design of ceramic coatings to enhance coating life and coated component life

• Successful incorporation of 5 main stress drivers into Thermal Barrier Coating (TBC) model, including oxidation
• First fundamental description of the role of oxidation in TBC failure
• Provided first basic statistical descriptors for quantifying interactive material property effects
• Provided basis for NASA TBC design innovation, patent pending

• In use to analyze test results and design TBCs for electric power generation turbine applications
• Commercial contract in excess of $10K was initiated prior to completion of Phase II work
• Strong commercial interest in future analysis based on the success of an exploratory contract
• This SBIR project resulted in an increase in employment, from 2 to 3 employees

• Presently in use to define failure mechanisms in TBCs
• Continued use to reduce costly experimentation while developing new TBC concepts
• In support of NASA HITEMP and Hybrid-Hyperspeed programs
