Study on water corrosion behavior of ZrSiO4 materials
Abstract ZrSiO4 bulk was prepared by pressureless sintering process and ZrSiO4 coating was deposited on the SiCf/SiC substrate using air plasma method. The microstructures of ZrSiO4 bulk and ZrSiO4 coating are both dense. A preliminary study of a water vapor corrosion test for ZrSiO4 bulk and ZrSiO4...
