Identifying Ceramic Corrosion
Corroded Surface of Sintered YBa2Cu3O7.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.
Corrosion of Alumina CeramicsOften used as a reactor material in Supercritical Water Oxidation at temperatures of 500C and pressures up to 30MPa.
Impurities in the Alumina Ceramic can leach into the solution and create acids.
4Importance of Application Method
Ti and B4C applied by RPS
Ti and B4C applied by LPPS
Y2O3 protected Zirconium Oxide
ConclusionLeaching is an important factor
Impurities and porosity lead to leaching
Method of application must be thoroughly researched for any application of ceramics
