Abstract:
An article includes a body that is coated with a ceramic coating. The ceramic coating may include Y2O3 in a range between about 45 mol % to about 99 mol %, ZrO2 in a range between about 0 mol % to about 55 mol %, and Al2O3 in range between about 0 mol % to about 10 mol %. The ceramic coating may alternatively inculde Y2O3 in a range between about 30 mol % to about 60 mol %, ZrO2 in a range between about 0 mol % to about 20 mol %, and Al2O3 in a range between about 30 mol % to about 60 mol %.
