  • Publication number: 20130288037
    Abstract: In an optimized method to apply a plasma sprayed coating of a yttrium containing oxide onto an article, a plasma power of between about 89-91 kW is selected for a plasma spraying system. Gas is flowed through the plasma spraying system at a selected gas flow rate of about 115-130 L/min. Ceramic powder comprising a yttrium containing oxide is fed into the plasma spraying system at a selected powder feed rate of about 10-30 g/min. A yttrium dominant ceramic coating is then formed on the article based on the selected power, the selected gas flow rate and the selected powder feed rate.

  • Publication number: 20130273327
    Abstract: To manufacture a ceramic article, a ceramic body comprising Al2O3 is roughened to a roughness of approximately 140 micro-inches (?in) to 240 ?in. The ceramic body is subsequently cleaned and then coated with a ceramic coating. The ceramic coating comprises a compound of Y4Al2O9 (YAM) and a solid solution of Y2-xZrxO3. The ceramic coating is then polished.
