MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202441057332 A) filed by Carborundum Universal Limited on January 29, 2025, for Thermal Spray Powders For Erosion Resistant Cmas Coatings, Erosion Resistant Cmas Coatings And Methods Of Fabricating The Same.
Inventors include Dr. Subramaniam Rangaswamy; Sivakumaran Maruvakkat Vasudevan; Ponnarassery Sukumaran Jayan; and Premnath Kunnath Nelloli.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The present invention relates to new and improved thermal barrier coating compositions that are also erosion resistant to CMAS attack at high temperatures. More specifically, this invention provides ceramic powder compositions which, when applied as thermal barriers in aviation-based or land-based turbine components, have improved erosion resistance, and also resistance to the attack by molten CMAS deposits. Currently used ceramic compositions based on Pyrochlores of the type Ln2Zr2O7 (where Ln= Gd, La, Sm, Nd, Eu and/or Yb) and/or high Yttria containing Zirconia powders/coatings (e.g., 38 wt% Yttria to 55 wt% Yttria) are improved by the addition of 0.1-10 wt% of graphene and or graphene oxide.
