A coated substrate (100) is provided that can include a substrate defining a surface (103), and an abradable coating (106) on the surface (103) of the substrate. The abradable coating (106) can comprise La2-xAxMo2-y-y'WyByO9-d forming a crystalline structure, where A comprises Li, Na, K, Rb, Cs, Sc, Y, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Th, Be, Mg, Ca, Sr, Ba, Cu, Bi, Cd, Zn, Ag, Au, Pt, Ir, Rh, Ru, Pd, or combinations thereof; 0 < x = about 0.2 (e.g., about 0.1 = x = about 0.15); 0 = y = about 1.5 (e.g., about 0.01 = y = about 1.5); B comprises Ta, Nb, V, Fe, Cr, Mn, Co, Ni, Sn, Ga, Al, Re, In, S, or combinations thereof; 0 = y' = about 0.2, wherein the sum of y and y' is about 0.01 to about 1.6; and 0 = d = about 0.2. |
