    Abstract: A multilayer thermal barrier coating (TBC) may include a plurality of layers selected to provide properties to the multilayer TBC. For example, a multilayer TBC may include a first layer deposited over a substrate, a second layer deposited over the first layer and a third layer deposited over the second layer. The first layer may be selected to provide thermal cycling resistance, the second layer may be selected to provide low thermal conductivity and the third layer may be selected to provide at least one of erosion resistance and CMAS degradation resistance. The multilayer TBC may also include two layers, or more than three layers.

    Abstract: A static chemical vapor deposition (CVD) process may be used to deposit a coating including a γ-Ni+γ′-Ni3Al phase constitution over a substrate. A static CVD process is performed in a closed system that may include the substrate, and coating material and an activator. The γ-Ni+γ′-Ni3Al coating may be modified by one or more additional elements, including, for example, Hf, Y, Zr, Ce, La, Si, Cr, Pt, or additional elements present in the substrate. A static CVD process may include co-deposition of two or more elements, and may also include sequential static CVD steps, each of which is performed in a closed system.

    Abstract: An article may include a superalloy substrate and a calcia-magnesia-alumina-silicate (CMAS)-resistant thermal barrier coating (TBC) layer overlying the superalloy substrate. In some embodiments, the CMAS-resistant TBC layer includes between about 50 wt. % and about 90 wt. % of a TBC composition and between about 10 wt. % and about 50 wt. % of a CMAS-resistant composition. In some examples, the TBC composition includes at least one of yttria-stabilized zirconia, yttria-stabilized hafnia, zirconia stabilized with at least three rare earth oxides, or hafnia stabilized with at least three rare earth oxides. In some examples, the CMAS-resistant composition includes alumina, silica, and an oxide of at least one of Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Yb, Dy, Ho, Er, Tm, Tb, or Lu.
