  1. Corrosion of Ceramics By Brian Cox For ME 406 Professor Sandwith Professor Kent

  2. Ceramics Reduce Corrosion Ceramics are used to protect machines in extreme conditions • Turbine Blades • Heat Exchanger Tubes

  3. Identifying Ceramic Corrosion Under extreme conditions it is necessary to understand the mechanisms which cause the break down of ceramics. Here Secondary Ion Mass Spectrometry (SIMS) is used to analyze the various types of corrosion of YBa2Cu3O7. Corroded Surface of Sintered YBa2Cu3O7.

  4. Corrosion of Alumina Ceramics Often used as a reactor material in Supercritical Water Oxidationat temperatures of 500˚C and pressures up to 30MPa. Impurities in the Alumina Ceramic can leach into the solution and create acids.

  5. Importance of Application Method Ti and B4C applied by LPPS Ti and B4C applied by RPS Y2O3 protected Zirconium Oxide

  6. Conclusion • Leaching is an important factor • Impurities and porosity lead to leaching • Method of application must be thoroughly researched for any application of ceramics
