Abstract (en)
Coated components (285), along with methods of their formation, are provided. The coating (202) may include a component (280) having a surface (281) and a coating (202) over the surface (281) of the component (280). The coating (202) may include a first plurality of coarse micrograins (291) having an coarse median grain size of greater than 10 µm to 20 µm, a second plurality of medium micrograins (293) having a medium median grain size of 4 µm to 10 µm, a third plurality of fine micrograins (294) having a fine median grain size of 0.001 µm to less than 4 µm. Each of the coarse micrograins (291), medium micrograins (293), and fine micrograins (294) may include, independently, a yttria-stabilized zirconia (YSZ) constituent having a chemical formula of (ZrO<sub>2</sub>)<sub>(1-x)</sub>(Y<sub>2</sub>O<sub>3</sub>)<sub>x</sub> with x is from greater than 0 to less than 1.
