Zusammenfassung:	An article includes a body having a plasma-sprayed ceramic coating on a surface thereof. The body can be formed of at one least one of the following materials: Al, Al2O3, AlN, Y2O3, YSZ, or SiC. The plasma-sprayed ceramic coating can include at least one of Y2O3, Y4Al2O9, Y3Al5O12 or a solid-solution of Y2O3 mixed with at least one of ZrO2, Al2O3, HfO2, Er2O3, Nd2O3, Nb2O5, CeO2, Sm2O3 or Yb2O3. The plasma-sprayed ceramic coating can further include splats.
