Title

Coated article and method of making

Short Description A modifier component can be added to a mullite coating to reduce cracks in the coating applied to a silicon-containing substrate
Abstract The present invention is based on the discovery that a modifier component can be added to a mullite coating to reduce cracks in the coating applied to a silicon-containing substrate. The modified mullite coating reduces fracture at the interface of the mullite coating and the silicon-containing substrate.

Commercial Applications
  • The modified mullite coating functions as a bond coat between the external environmental/thermal barrier coating and the silicon-containing substrate for use in high temperature industrial applications.
Advantages
  • Reduction of cracks in the mullite coating.
