Abstract: A method for fabricating thermal barrier coatings. The thermal barrier coatings are produced with a fine grain size by reverse co-precipitation of fine powders. The powders are then sprayed by a solution plasma spray that partially melts the fine powders while producing a fine grain size with dense vertical cracking. The coatings comprise at least one of 45%-65% Yb2O3 the balance zirconia (zirconium oxide), Yb/Y/Hf/Ta the balance zirconia (zirconium oxide) and 2.3-7.8% La, 1.4-5.1% Y and the balance zirconia (zirconium oxide) and are characterized by a thermal conductivity that is about 25-50% lower than that of thermal barrier coatings comprising YSZ. The thermal barrier coatings also are characterized by at least one of excellent erosion resistance, fracture toughness and abrasion resistance.
