Abstract: A method for coating a substrate includes suspension plasma spraying of a size distribution of a ceramic powder of essentially uniform chemical composition to form a first ceramic layer. The size distribution has a trough spanning a transition size for powder behavior of gas-flow trajectories of smaller particles and ballistic trajectories of larger particles.

Abstract: In one aspect, a calcium-magnesium alumino-silicate (CMAS)-resistant coating includes an outer coating having a plurality of columnar structures formed during material deposition due to preferential material accumulation and a plurality of generally vertically-oriented gaps separating adjacent columnar structures. The columnar structures include a plurality of randomly-oriented particle splats and a CMAS-reactive material and have a total porosity of less than five percent. The plurality of generally vertically-oriented gaps extend from an outermost surface of the outer coating to a first depth of the outer coating equal to or less than a total thickness of the outer coating. The vertically-oriented gaps have a median gap width of less than five micrometers.

Abstract: A strain-tolerant coating for use in gas turbine engines can include a plurality of dense, generally vertically-oriented columnar structures formed during deposition by preferential material accumulation, and a plurality of inter-columnar gaps separating the columnar structures. The columnar structures can include a plurality of randomly-oriented particle splats and can have a porosity of less than four percent.

Abstract: A process for coating a component and a coating system including a bond coat on a superalloy substrate. A thermal barrier material may be applied to the bond coat and a rare earth apatite may be applied to the thermal barrier material via one of Suspension Plasma Spray (SPS) and Solution Precursor Plasma Spray (SPPS) to form an exposed surface. The rare earth apatite may be formed as Ca2+yRE8+x(SiO4)6O2+3x/2+y in which −2
